Check Digit Verification of cas no
The CAS Registry Mumber 137896-94-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,8,9 and 6 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 137896-94:
(8*1)+(7*3)+(6*7)+(5*8)+(4*9)+(3*6)+(2*9)+(1*4)=187

Synthesis of Globotriaosylceramide (Gb3) and Isoglobotriaosylceramide (isoGb3)
Qiu, Dongxu,Schmidt, Richard R.
, p. 217 - 224 (2007/10/02)
The synthesis of globotriaosylceramide (1) was based on O-galactosyl trichloroacetimidate 5α as donor and 4b-O-unprotected lactose 7 as acceptor; 7 was readily accessible from lactose.Glycosylation by an "inverted procedure" afforded preferentially the α-
