Check Digit Verification of cas no
The CAS Registry Mumber 180524-39-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,5,2 and 4 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 180524-39:
(8*1)+(7*8)+(6*0)+(5*5)+(4*2)+(3*4)+(2*3)+(1*9)=124
124 % 10 = 4
So 180524-39-4 is a valid CAS Registry Number.

A practical method for the synthesis of sialyl α-glycosides
Martichonok, Valeri,Whitesides, George M.
, p. 8187 - 8191 (1996)
Addition of 2,4-dimethylbenzenesulfenyl chloride to sialic acid glycal gives crystalline 2-chloro-3-thiosialic acid 3 in 85% yield. Reaction of 3 with sodium thiomethoxide in acetonitrile at 0°C affords the sialic acid donor α-2-(methylthio)-3-thiosialic
