109900-92-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109900-92-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,0 and 0 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 109900-92:
(8*1)+(7*0)+(6*9)+(5*9)+(4*0)+(3*0)+(2*9)+(1*2)=127
127 % 10 = 7
So 109900-92-7 is a valid CAS Registry Number.

FREE RADICAL ANNULATION OF CYCLOPENTANE RING
Cekovic, Zivorad,Saicic, Radomir
, p. 5893 - 5896 (2007/10/02)
Homoallyl radical, e.g. 2, reacts with an electron-deficient olefinic bond 1 with a new C-C bond forming and arising of a 5-hexenyl radical 3 which further undergoes to 5-exo-trigonal cyclization with a cyclopentane ring (4) annulation.
