887947-00-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 887947-00-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,7,9,4 and 7 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 887947-00:
(8*8)+(7*8)+(6*7)+(5*9)+(4*4)+(3*7)+(2*0)+(1*0)=244
244 % 10 = 4
So 887947-00-4 is a valid CAS Registry Number.

Radical-mediated 5-exo-trig cyclizations of 3-silylhepta-1,6-dienes
James, Philippe,Schenk, Kurt,Landais, Yannick
, p. 3630 - 3633 (2007/10/03)
Regioselectivity of the sulfonyl radical mediated 5-exo-trig cyclization of 3-silylheptadienyl systems 3a-d has been studied. At low temperature, the reaction of the sulfonyl radical occurs regioselectively at the allylsilane terminus, while a reversal of
