Check Digit Verification of cas no
The CAS Registry Mumber 120413-57-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,4,1 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 120413-57:
(8*1)+(7*2)+(6*0)+(5*4)+(4*1)+(3*3)+(2*5)+(1*7)=72
72 % 10 = 2
So 120413-57-2 is a valid CAS Registry Number.

Facile synthesis of 2-alkylthio-3-alkyl-5-phenylmethylidene-4H-imidazol-4- ones
Sun, Yong,Gao, Li-Ping,Ding, Ming-Wu
, p. 1185 - 1191 (2007/10/03)
2-Alkylthio-3-alkyl-5-phenylmethylidene-4H-imidazol-4-ones 6 were synthesized by N-alkylation and S-alkylation of 2-thioxo-5-phenylmethylidene-4- imidazolidinone 5, which was obtained via cyclization of vinyl isothiocyanate 4 with excess ammonium hydroxid
