Check Digit Verification of cas no

The CAS Registry Mumber 191659-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,6,5 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 191659-40:
(8*1)+(7*9)+(6*1)+(5*6)+(4*5)+(3*9)+(2*4)+(1*0)=162
162 % 10 = 2
So 191659-40-2 is a valid CAS Registry Number.

Glycosylation of 2-thiouracil derivatives. A synthetic approach to 3- glycosyl-2,4-dioxypyrimidines

Khodair,Ibrahim,El Ashry

, p. 433 - 444 (1997)

Reaction of 6-aryl-5-cyano-2-thiouracils 2a-d with glycosyl halides 4a,b under alkaline conditions gave the respective bisglycosylated derivatives 5a- h. However, their deacetylation with ammonia in methanol caused a cleavage of the S-glycosyl residue and gave the N-3 glycosylated analogues 6a-h.
