Check Digit Verification of cas no
The CAS Registry Mumber 84730-56-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,7,3 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 84730-56:
(7*8)+(6*4)+(5*7)+(4*3)+(3*0)+(2*5)+(1*6)=143
143 % 10 = 3
So 84730-56-3 is a valid CAS Registry Number.

SYNTHESIS OF DERIVATIVES OF METHYL β-SOPHOROSIDE
Takeo, Ken'ichi
, p. 73 - 84 (2007/10/02)
Selective tritylation of methyl β-sophoroside (1) and subsequent acetylation gave the 3,4,2',3',4'-penta-O-acetyl-6,6'-di-O-trityl derivative, which was O-detritylated, and the product p-toluenesulfonylated, to give methyl 3,4,2',3',4'-penta-O-acetyl-6,6'
