Check Digit Verification of cas no

The CAS Registry Mumber 81023-74-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,0,2 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 81023-74:
(7*8)+(6*1)+(5*0)+(4*2)+(3*3)+(2*7)+(1*4)=97
97 % 10 = 7
So 81023-74-7 is a valid CAS Registry Number.

REACTIVITY OF TRIFORMYLMETHANE. I. REACTIONS OF TRIFORMYLMETHANE WITH SELECTED TYPES OF AMINO COMPOUNDS

Arnold, Zdenek,Budesinsky, Milos,Pankova, Magdalena

, p. 1019 - 1031 (2007/10/02)

Reactions of triformylmethane with various types of amino compounds were investigated.Besides with ammonia, triformylmethane reacts spontaneously with primary amines, amino acids and their esters, urea and related compounds including carbamic acid derivatives.Reactions with amides of carboxylic and sulfonic acids require catalysis with Lewis acids.Primary products are aminomethylenemalonaldehyde derivatives IIIa-IIIv.Reactions of triformylmethane with excess of selected primary amines and two secondary amines (dimethylamine and morpholine) were also studied.
