Check Digit Verification of cas no

The CAS Registry Mumber 164664-96-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,4,6,6 and 4 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 164664-96:
(8*1)+(7*6)+(6*4)+(5*6)+(4*6)+(3*4)+(2*9)+(1*6)=164
164 % 10 = 4
So 164664-96-4 is a valid CAS Registry Number.

Fast and efficient microwave synthetic methods for some new 2(1H)-pyridone arabinosides

Abdou, Ibrahim M.,Rateb, Nora M.,Eldeab, Hany A.

, p. 135 - 141 (2012)

Two series of novel 3-cyano-2-(2'' ,3'' ,4'' -tri- O - acetyl- β - d -arabinopyranosyloxy)pyridones 5a - h and 9a,b were synthesized. Microwave irradiation has been used to obtain these products in high yield under milder conditions by the reaction of 2(1 H )-pyridone or its salt with an activated arabinose. The silyl method was used to obtain the same nucleosides 5a - h and 9a,b . Triethylamine was used to remove the acetyl protecting groups from the sugar moiety and to produce the free nucleosides 6a - h and 10a,b in 85 - 91% yield.
