Check Digit Verification of cas no

The CAS Registry Mumber 1448820-15-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,8,8,2 and 0 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1448820-15:
(9*1)+(8*4)+(7*4)+(6*8)+(5*8)+(4*2)+(3*0)+(2*1)+(1*5)=172
172 % 10 = 2
So 1448820-15-2 is a valid CAS Registry Number.

Synthesis of novel 1-[(1-ethoxymethylene)amino]imidazol-5(4H)-ones and 1,2,4-triazin-6(5H)-ones from optically active α-aminocarboxylic acid hydrazides

Kudelko, Agnieszka,Zieliński, Wojciech,Jasiak, Karolina

, p. 4637 - 4640 (2013/08/23)

New derivatives of 1-[(1-ethoxymethylene)amino]imidazol-5(4H)-one and 1,2,4-triazin-6(5H)-one were synthesized via reactions of optically active α-aminocarboxylic acid hydrazides and triethyl orthoesters in xylene. The factors influencing the formation of the unexpected five-membered products and attempts to elucidate the mechanism are discussed.
