535961-80-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 535961-80-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,3,5,9,6 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 535961-80:
(8*5)+(7*3)+(6*5)+(5*9)+(4*6)+(3*1)+(2*8)+(1*0)=179
179 % 10 = 9
So 535961-80-9 is a valid CAS Registry Number.

Efficient synthesis of bromocyclopenta[b]indoles via a bromination - Reduction sequence
Lachance, Nicolas,Chan, Wing Yan
, p. 289 - 295 (2003)
Substituted cyclopenta[b]indoles are selectively brominated in good yields with excess pyridine - Br2 charge-transfer complex (PyBr2) in a one-pot reaction to provide 5 and/or 7-bromoindoles. The mechanism involves the formation of a
