129207-49-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129207-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,2,0 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 129207-49:
(8*1)+(7*2)+(6*9)+(5*2)+(4*0)+(3*7)+(2*4)+(1*9)=124
124 % 10 = 4
So 129207-49-4 is a valid CAS Registry Number.

Synthesis of Novel 1H-Imidazobenzazepine-1,3(2H)-dione and Pyrimidobenzazepine-1,3,4(2H)-trione
Gallaschun, Randall J.,Schnur, Rodney C.
, p. 963 - 966 (2007/10/02)
Two novel tricyclic systems derived from 3-benzazepines were synthesized; the first, a 6,7,5-ring, 1H-imidazobenzazepine-1,3(2H)-dione was obtained using an unusual Stiles reaction while the second, an analogous 6,7,6-ring, pyrimidoben
