289486-07-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 289486-07-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,4,8 and 6 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 289486-07:
(8*2)+(7*8)+(6*9)+(5*4)+(4*8)+(3*6)+(2*0)+(1*7)=203
203 % 10 = 3
So 289486-07-3 is a valid CAS Registry Number.

, p. 867 - 879 (2007/10/03)
2-Substituted allyl alcohols 9 and 14 were prepared starting from butane-1,2,4-triol and glycerol, respectively. Mitsunobu condensations of 9 and 14 with purine and pyrimidine bases, followed by deprotection, afforded a number of acyclonucleosides having
