Check Digit Verification of cas no

The CAS Registry Mumber 163772-71-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,7,7 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 163772-71:
(8*1)+(7*6)+(6*3)+(5*7)+(4*7)+(3*2)+(2*7)+(1*1)=152
152 % 10 = 2
So 163772-71-2 is a valid CAS Registry Number.

Preparation of polycyclic systems by sequential 5-exo-digonal radical cyclization, 1,5-hydrogen transfer from silicon, and 5-endo-trigonal cyclization

Clive,Yang,Macdonald,Wang,Cantin

, p. 1966 - 1983 (2007/10/03)

Radicals of type 1 undergo 5-exo diagonal cyclization, and the resulting vinyl radical abstracts hydrogen from silicon to afford a silicon-centered radical. This radical closes in a 5-endo trigonal manner to generate radicals of type 4, which are reduced

5-endo-Trigonal Radical Cyclisation - a General Procedure for Making Five-Membered Rings

Clive, Derrick L. J.,Cantin, Michel

, p. 319 - 320 (2007/10/02)

Silicon-centred radicals, derived from alkoxy dialkyl silanes by intramolecular hydrogen transfer, undergo 5-endo-trigonal closure.
