198637-36-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 198637-36-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,6,3 and 7 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 198637-36:
(8*1)+(7*9)+(6*8)+(5*6)+(4*3)+(3*7)+(2*3)+(1*6)=194
194 % 10 = 4
So 198637-36-4 is a valid CAS Registry Number.

Tandem radical cyclizations promoted by O-stannyl ketyls
Enholm, Eric J.,Burroff, Janet A.
, p. 13583 - 13602 (2007/10/03)
This work summarizes an investigation of tandem radical cyclizations triggered by O-stannyl ketyls. This organometallic reactive intermediate is prepared from the reaction of tributyltin hydride (nBu3SnH) with a carbonyl functional group by a f
