110905-59-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 110905-59-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,9,0 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 110905-59:
(8*1)+(7*1)+(6*0)+(5*9)+(4*0)+(3*5)+(2*5)+(1*9)=94
94 % 10 = 4
So 110905-59-4 is a valid CAS Registry Number.

Synthesis of Dialkyl (2,3-Epoxy-4-oxoalkyl)phosphonates from (1-Formylalkyl)phosphonates
Oehler, Elisabeth,Kang, Heun-Soo,Zbiral, Erich
, p. 299 - 308 (2007/10/02)
Starting with dialkyl (1-formylalkyl)phosphonates 1, the formerly unknown trans-(2,3-epoxy-4-oxoalkyl)phosphonates 5 are obtained on two ways: Compounds with R1 = R2 = H or Me and R3 = alkyl (5b-e and 5k) are prepared in v
