Check Digit Verification of cas no

The CAS Registry Mumber 103218-08-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,2,1 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 103218-08:
(8*1)+(7*0)+(6*3)+(5*2)+(4*1)+(3*8)+(2*0)+(1*8)=72
72 % 10 = 2
So 103218-08-2 is a valid CAS Registry Number.

DERIVATIVES OF IMINOMALONIC ESTER

Prosyanik, A. V.,Fedoseenko, D. V.,Markov, V. I.

, p. 1494 - 1503 (2007/10/02)

The synthesis of (alkylimino)malonic esters was realized by the reaction of alkylamines with mesoxalic or dibromomalonic ester. (Halogenimino)malonic esters were obtained for the first time by the reaction of aminomalonic ester with tert-butyl hypochlorite or sodium hypobromite.A new method was developed for the synthesis of (acylimino)malonic esters by the successive bromination and dehydrobromination of (acylamino)malonic esters.The addition of various nucleophiles (water, amines, formamide) at the C=N bond of (acylimino)malonic esters was studied.
