Check Digit Verification of cas no

The CAS Registry Mumber 407627-18-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,7,6,2 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 407627-18:
(8*4)+(7*0)+(6*7)+(5*6)+(4*2)+(3*7)+(2*1)+(1*8)=143
143 % 10 = 3
So 407627-18-3 is a valid CAS Registry Number.

Novel synthesis of 1,2,4-triazolo[4,3-a]pyrimidin-5-one derivatives

Hassaneen, Hamdi M,Abdelhadi, Hyam A,Abdallah, Tayseer A

, p. 10133 - 10138 (2001)

1,2-Dihydro-2-thioxopyrimidin-4(3H)ones 6 react with C-ethoxycarbonyl-N-arylhydrazonoyl chlorides 1 to give 1,2,4-triazolo[4,3-a]pyrimidines 11 in good yield. The latter products 11 react with benzenediazonium chloride, nitrous acid, acetyl chloride and chloroacetyl chloride to give the corresponding substitution products 16-18. The structures of the newly synthesized compounds are established on the basis of chemical and spectroscopic evidence.
