Check Digit Verification of cas no

The CAS Registry Mumber 51300-33-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,3,0 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 51300-33:
(7*5)+(6*1)+(5*3)+(4*0)+(3*0)+(2*3)+(1*3)=65
65 % 10 = 5
So 51300-33-5 is a valid CAS Registry Number.

Reactions of 2-aminothiobenzamide with isocyanates: A new synthesis of 2,3-dihydroimidazo[1,2-c]quinazolin-5(6H)-one and 3,4-dihydro-2H-pyrimido[1,2-c]quinazolin-6(7H)-one

Shiau,Chern,Tien,Liu

, p. 595 - 596 (2007/10/02)

2-(2-Chloroethylureido)- and 2-(3-chloropropylureido)thiobenzamides 5a,b were prepared in good yields by treating 2-aminothiobenzamide with 2-chloroethyl and 3-chloropropyl isocyanates respectively. Subsequent treatment of compound 5a and 5b either with alkali or mineral acid led to the formation of 2,3-dihydro-imidazo[1,2-c]quinazolin-5(6H)-one 7a and 3,4-dihydro-2H-pyrimido[1,2-c]quinazolin-6(7H)-one 7b.
