Check Digit Verification of cas no

The CAS Registry Mumber 19181-34-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,1,8 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 19181-34:
(7*1)+(6*9)+(5*1)+(4*8)+(3*1)+(2*3)+(1*4)=111
111 % 10 = 1
So 19181-34-1 is a valid CAS Registry Number.

Improved synthesis of methyl- and phenyl-substituted pyrido[2,3-d]pyrimidine-2,4-diamines

Troschutz,Dennstedt

, p. 221 - 224 (1994)

The title compounds 4b-g, 10a,b and 13 can be prepared in improved yields by 'cyclocondensation' of the 1,3-biselectrophiles 1a-e, 5b,f,g, 7b,d, 8a,b, and 12 with 2,4,6-triaminopyrimidine (2).
