138793-34-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138793-34-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,7,9 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 138793-34:
(8*1)+(7*3)+(6*8)+(5*7)+(4*9)+(3*3)+(2*3)+(1*4)=167
167 % 10 = 7
So 138793-34-7 is a valid CAS Registry Number.

Radical Cyclizations of Geminal Radical Precursors
Clive, Derrick L. J.,Cole, Derek C.
, p. 3263 - 3270 (2007/10/02)
Polycyclic structures can be generated by double radical cyclization, using compounds having two groups, capable of being homolysed, attached to a single carbon that is suitably located with respect to two unsaturated pendants.
