Check Digit Verification of cas no

The CAS Registry Mumber 187157-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,1,5 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 187157-31:
(8*1)+(7*8)+(6*7)+(5*1)+(4*5)+(3*7)+(2*3)+(1*1)=159
159 % 10 = 9
So 187157-31-9 is a valid CAS Registry Number.

Stereocontrolled syntheses of O-glycans of core class 2 with a linear tetrameric lactosamine chain and with three lactosamine branches

Wang, Zhi-Guang,Zhang, Xu-Fang,Ito, Yukishige,Nakahara, Yoshiaki,Ogawa, Tomoya

, p. 25 - 39 (1996)

Synthetic routes to O-glycans of core class 2 with a linearly extended tetralactosamine moiety and with three lactosamine branches are discussed. By a glycosyl fluoride-method, the mono- and the di-lactosaminyl units were attached to the core disaccharide (Galβ1→3GalN3) derivatives in high stereoselectivity.
