119288-70-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119288-70-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,2,8 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 119288-70:
(8*1)+(7*1)+(6*9)+(5*2)+(4*8)+(3*8)+(2*7)+(1*0)=149
149 % 10 = 9
So 119288-70-9 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.
