Check Digit Verification of cas no

The CAS Registry Mumber 33032-80-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,0,3 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 33032-80:
(7*3)+(6*3)+(5*0)+(4*3)+(3*2)+(2*8)+(1*0)=73
73 % 10 = 3
So 33032-80-3 is a valid CAS Registry Number.

Novel Synthesis of Aryl 2,3,4,6-Tetra-O-acetyl-D-glucopyranosides

Yamaguchi, Masahiko,Horiguchi, Akira,Fukuda, Akira,Minami, Toru

, p. 1079 - 1082 (2007/10/02)

The glucosidation of phenols with 2,3,4,6-tetra-O-acetyl-α-D-glucopyranosyl fluoride in the presence of BF3*OEt2 to give, predominantly, α-anomers has been studied.In the presence of an amine base, 1,1,3,3-tetramethylguanidine, however, enhanced β-selectivity was achieved.The former reaction provides a novel and useful synthesis of aryl 2,3,4,6-tetra-O-acetyl-α-D-glucopyranoside whilst the latter is effective for the glycosidation of relatively hindered phenols.
