Check Digit Verification of cas no
The CAS Registry Mumber 918331-14-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,8,3,3 and 1 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 918331-14:
(8*9)+(7*1)+(6*8)+(5*3)+(4*3)+(3*1)+(2*1)+(1*4)=163
163 % 10 = 3
So 918331-14-3 is a valid CAS Registry Number.

Synthesis and biological evaluation of novel pyrrolopyrrolizinones as anticancer agents
Rochais,Lisowski,Dallemagne,Rault
, p. 8162 - 8175 (2007/10/03)
We herein describe the synthesis of novel 3-(het)aryl-pyrrolo[2,3-b]pyrrolizin-8(1H)-ones starting from commercial (het)aryl-acetonitriles. A more convergent route was also described through the first synthesis of ethyl 3-amino-4-bromo-1H-pyrrole-2-carbox
