34255-80-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 34255-80-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,2,5 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 34255-80:
(7*3)+(6*4)+(5*2)+(4*5)+(3*5)+(2*8)+(1*0)=106
106 % 10 = 6
So 34255-80-6 is a valid CAS Registry Number.

Motoyoshiya, Jiro,Hirata, Kozo
, p. 211 - 214 (2007/10/02)
Methyl- and chloro(diethylphosphono)ketenes were found to add to cyclopentadiene or imines in unusual manner in the certain cases.Some chemical conversions and the Horner-Wittig reaction of the cycloadducts were examined.
