Check Digit Verification of cas no

The CAS Registry Mumber 227751-12-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,7,7,5 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 227751-12:
(8*2)+(7*2)+(6*7)+(5*7)+(4*5)+(3*1)+(2*1)+(1*2)=134
134 % 10 = 4
So 227751-12-4 is a valid CAS Registry Number.

Regio- and stereoselective synthesis of oligosaccharides with acetobromolactose and acetobromomaltose as glycosyl donors via orthoester intermediates

Wang, Wei,Kong, Fanzuo

, p. 451 - 460 (2007/10/03)

Regio- and stereoselective synthesis of some trisaccharides was effected in high yields from coupling of acetobromolactose or acetobromomaltose as donors with partially protected glucoside acceptors through an orthoester formation-rearrangement strategy. Selective 1→6 or 1→3 with 1,2-trans glycosylation was achieved.
