Check Digit Verification of cas no
The CAS Registry Mumber 898808-42-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,8,8,0 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 898808-42:
(8*8)+(7*9)+(6*8)+(5*8)+(4*0)+(3*8)+(2*4)+(1*2)=249
249 % 10 = 9
So 898808-42-9 is a valid CAS Registry Number.

Synthesis of galactosaminyl d-chiro-inositols
Marnera, Georgia,d'Alarcao, Marc
, p. 1105 - 1116 (2007/10/03)
All six isomeric d-galactosaminopyranosyl-d-chiro-inositols have been prepared by glycosylation of appropriate penta-O-benzyl-d-chiro-inositols. The three requisite protected d-chiro-inositols were prepared by SmI2-promoted pinacol coupling of
