Check Digit Verification of cas no

The CAS Registry Mumber 80956-42-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,9,5 and 6 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 80956-42:
(7*8)+(6*0)+(5*9)+(4*5)+(3*6)+(2*4)+(1*2)=149
149 % 10 = 9
So 80956-42-9 is a valid CAS Registry Number.

Trityl Derivatives of Cellobiose. VI. Unambiguous Assignments of Acetoxyl Group Resonances in the 1H-NMR Spectra of 6,6'-Di-O-trityl-, 6-O-Trityl-, and 6'-O-Tritylcellobiose Peracetates

Koizumi, Kyoko,Utamura, Toshiko

, p. 2791 - 2798 (2007/10/02)

The 1H-NMR spectra of 6,6'-di-O-trityl-, 6-O-trityl-, and 6'-O-tritylcellobiose peracetates (I-1, II-1, and III-1) showed some of the acetoxyl group resonances at abnormally high fields in CDCl3 and all their acetoxyl group signals were resolved in the re
