Check Digit Verification of cas no

The CAS Registry Mumber 197649-30-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,6,4 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 197649-30:
(8*1)+(7*9)+(6*7)+(5*6)+(4*4)+(3*9)+(2*3)+(1*0)=192
192 % 10 = 2
So 197649-30-2 is a valid CAS Registry Number.

Studies on the synthesis of two tetrasaccharides and the reactivity difference between them

Zhu, Xiao-Xiang,Cai, Meng-Shen,Zhou, Rou-Li

, p. 261 - 266 (2007/10/03)

Studies on the reactivity of two synthetic tetrasaccharides as glycosyl acceptors showed that condensation of the methyl α-glycoside with a disaccharide donor afforded a hexasaccharide, but condensation of the methyl β-glycoside with the disaccharide did not yield the corresponding hexasaccharide under the same conditions. A combination of theoretical results and 2D NMR indicated that the reactivity difference between the methyl α-glycoside and the methyl β-glycoside was determined mainly by steric effects.
