124288-67-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 124288-67-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,2,8 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 124288-67:
(8*1)+(7*2)+(6*4)+(5*2)+(4*8)+(3*8)+(2*6)+(1*7)=131
131 % 10 = 1
So 124288-67-1 is a valid CAS Registry Number.

One-pot synthesis of novel 2′-deoxyuridine derivatives containing α-aminophosphonate moieties

Shang, Zhi-Qiang,Chen, Ru-Yu,Huang, You

, p. 230 - 235 (2007)

A series of α-aminophosphonate derivatives of 2′-deoxyuridine (8a-k) have been prepared from 5′-O-tert-butyldimethylsilyl-3′- amino-2′, 3′-dideoxyuridine in good yields. The structures of all the products were confirmed by 1H NMR, 31

Conversion of Some Pyrimidine 2'-Deoxyribonucleosides into the Corresponding 2',3'-Didehydro-2',3'-dideoxynucleosides

Joshi, Bhalchandra V.,Rao, T. Sudhakar,Reese, Colin B.

, p. 2537 - 2544 (2007/10/02)

Thymidine 4b was converted into 2,3'-anhydro-1-(2'-deoxy-β-D-threo-pentofuranosyl)thymine 7b in ca. 65percent isolated yield by being heated at 155 deg C with an excess of diphenyl sulfite and 1-methylimidazole in N,N-dimethylacetamide solution. 2'-Deoxyuridine 4a, 2'-deoxy-5-ethyluridine 4c and 2'-deoxy-5-fluorouridine 4d were similarly converted into 2,3'-anhydronucleosides which were isolated as their 5'-O-(tert-butyldimethylsilyl) derivatives 8a, 8c and 8d in 51, 50 and 59percent yield, respectively.When the oxetane derivatives 5a-d, prepared by the literature procedure from the parent 2'-deoxynucleosides 4a-d, were heated with an excess of sodium hydride in N,N-dimethylacetamide solution at 100 deg C, they were converted into the corresponding 2',3'-didehydro-2',3'-dideoxynucleosides 6a-d in 68, 76, 69 and 74percent isolated yield, respectively.The latter compounds were similarly prepared from the 2,3'-anhydronucleosides 7a-d in 71, 81, 69 and 74percent isolated yield, respectively. 2,3'-Anhydro-5'-O-(tert-butyldimethylsilyl)-2'-deoxy-5-(trifluoromethyl)- and -5-iodo-1-(β-D-threo-pentofuranosyl)uracil 8e and 8f, which were themselves prepared from the parent 2'-deoxynucleosides 4e and 4f, respectively, in ca. 60 and 50percent yield, were converted by a three-step procedure via the intermediate 2'-deoxy-3'-(phenylseleno) derivatives 10e and 10f into the corresponding 2',3'-didehydro-2',3'-dideoxynucleosides 6e and 6f in 52 and 49percent overall yield, respectively.Compound 8e was also converted into 2',3'-dideoxy-5-(trifluoromethyl)uridine 11b and 3'-azido-2',3'-dideoxy-5-(trifluoromethyl)uridine 11c in 49 and 66percent overall yield, respectively.
