Check Digit Verification of cas no

The CAS Registry Mumber 669772-64-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,9,7,7 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 669772-64:
(8*6)+(7*6)+(6*9)+(5*7)+(4*7)+(3*2)+(2*6)+(1*4)=229
229 % 10 = 9
So 669772-64-9 is a valid CAS Registry Number.

Synthesis of Anomeric Sulfur Analogues of CMP-Neu5Ac Containing Tethered Alkane or Arene

Chang, Kai-Hsuan,Tao, Ying Shin,Li, Wen-Shan

, p. 37 - 40 (2007/10/03)

A new approach to the synthesis of anomeric sulfur analogues of CMP-Neu5Ac containing alkane or arene linkage 1a-d is described. The procedure involves the high β-stereoselectivity in sialylation of the peracetylated sialic acid methyl ester 4 with mercap
