Check Digit Verification of cas no
The CAS Registry Mumber 313364-03-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,3,3,6 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 313364-03:
(8*3)+(7*1)+(6*3)+(5*3)+(4*6)+(3*4)+(2*0)+(1*3)=103
103 % 10 = 3
So 313364-03-3 is a valid CAS Registry Number.

, p. 532 - 536 (2000)
The scission of the urea group in 5-alkyl-2-amino-3,4-dicyano-N-ureidopyrroles on boiling in KOH solution in DMSO was observed to give 5-alkyl-1,2-diamino-3,4-dicyanopyrroles which were used for the synthesis of pyrrolo[1,2-b][1,2,4] triazepines by reacti
