99911-94-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99911-94-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,9,1 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 99911-94:
(7*9)+(6*9)+(5*9)+(4*1)+(3*1)+(2*9)+(1*4)=191
191 % 10 = 1
So 99911-94-1 is a valid CAS Registry Number.

Synthesis of Bicyclic 1,3,5-Triazine-2,4(3H)-diones: Reaction of Amidines with Diphenyl Iminodicarboxylate
Usui, Hiroyuki,Watanabe, Yoshifumi,Kanao, Munefumi
, p. 551 - 552 (2007/10/02)
The preparation of bicyclic 1,3,5-triazine-2,4(3H)-diones 3 has been investigated. Diphenyl iminodicarboxylate (2) reacted smoothly with cyclic amidines to give bicyclic triazinediones in good yields.
