Check Digit Verification of cas no

The CAS Registry Mumber 503159-56-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,1,5 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 503159-56:
(8*5)+(7*0)+(6*3)+(5*1)+(4*5)+(3*9)+(2*5)+(1*6)=126
126 % 10 = 6
So 503159-56-6 is a valid CAS Registry Number.

Synthesis of a spacer-armed disulfated tetrasaccharide of SB1a, a carbohydrate hapten associated with human hepatocellular carcinoma

Li, Qin,Li, Hui,Li, Qing,Lou, Qing-Hua,Su, Bin,Cai, Meng-Shen,Li, Zhong-Jun

, p. 1929 - 1934 (2002)

A disulfated tetrasaccharide fragment with a spacer arm of human hepatocellular carcinoma carbohydrate antigen SB1a, namely, 2-aminoethyl 3-O-sulfo-β-D-galactopyranosyl-(1→3)-2-acetamido-2-deoxy-β-D- galactopyranosyl-(1→4)-3-O-sulfo-β-D-galactopyranosyl-(1→4)- β-D-glucopyranoside was synthesized via a [2+1+1] block building mode. In the last coupling step toward the trisaccharide acceptor 8, benzoyl protected galactosyl bromide donor 14 was found to be much more reactive than the acetyl-protected donors.
