154885-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 154885-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,8,8 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 154885-40:
(8*1)+(7*5)+(6*4)+(5*8)+(4*8)+(3*5)+(2*4)+(1*0)=162
162 % 10 = 2
So 154885-40-2 is a valid CAS Registry Number.

Synthesis of benzocarbazoloquinones via oxidative cyclization
Rajeswaran,Srinivasan
, p. 270 - 272 (2007/10/02)
Ethyl 1-benzenesulfonyl-2-bromomethyl-5-methoxyindole-3-carboxylate (2) and 2-methyl-3-phenylthioindole (5) have been converted into benzcarbazoloquinones 4 and 10, respectively, involving an oxidative cyclization by air during the application of polyphos
