Check Digit Verification of cas no

The CAS Registry Mumber 909697-43-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,9,6,9 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 909697-43:
(8*9)+(7*0)+(6*9)+(5*6)+(4*9)+(3*7)+(2*4)+(1*3)=224
224 % 10 = 4
So 909697-43-4 is a valid CAS Registry Number.

Carbon-carbon bond formation by radical cyclization: Regioselective synthesis of spiro heterocyclic compounds by nBu3SnH- mediated reaction

Majumdar,Kundu

, p. 1879 - 1886 (2007/10/03)

Several spiro heterocyclic compounds have been regioselectively synthesized in excellent yield by n Bu 3 SnH-AIBN-mediated radical cyclization of 4-(2′-bromoaryloxymethyl)-1-methylquinolin-2(1 H )-ones in refluxing benzene under nitrogen for 4 h. Copyrigh
