Check Digit Verification of cas no

The CAS Registry Mumber 823806-72-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,2,3,8,0 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 823806-72:
(8*8)+(7*2)+(6*3)+(5*8)+(4*0)+(3*6)+(2*7)+(1*2)=170
170 % 10 = 0
So 823806-72-0 is a valid CAS Registry Number.

Glyoxylic acid and MP-glyoxylate: Efficient formaldehyde equivalents in the 3-CC of 2-aminoazines, aldehydes, and isonitriles

Lyon, Michael A.,Kercher, Timothy S.

, p. 4989 - 4992 (2007/10/03)

(Chemical Equation Presented) Glyoxylic acid, either in solution or immobilized on MP-carbonate (MP-glyoxylate), participates in an uncatalyzed 3-CC with 2-aminoazines and isonitriles to afford novel 2-unsubstituted-3-amino- imidazoheterocycles. MP-glyoxylate serves as a particularly efficient and experimentally convenient formaldehyde equivalent and readily liberates products through decarboxylation/self-release from the resin. These examples furthermore constitute the first application in which MP-CO3 serves as a solid support for transformations involving carboxylic acids.
