Check Digit Verification of cas no

The CAS Registry Mumber 109976-14-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,7 and 6 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 109976-14:
(8*1)+(7*0)+(6*9)+(5*9)+(4*7)+(3*6)+(2*1)+(1*4)=159
159 % 10 = 9
So 109976-14-9 is a valid CAS Registry Number.

Modification of Silica Gel by Derivatives of Tartaric Acid of High Stereoisomeric Purity and Characterisation by Solid-State 13C-NMR-CP-MAS Spektroscopy

Koppenhoefer, Bernhard,Allmendinger, Hans,Peters, Bernadette

, p. 991 - 995 (2007/10/02)

(Dissymmetric) tartaric acid of high stereoisomeric purity (99.3percent 2R,3R, 0.1percent 2S,3S, and 0.6percent meso, determined by GC on Chirasil-Val) is used for the synthesis of chirally modified silica phases.Two synthetic approaches have proven parti
