55949-57-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55949-57-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,9,4 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 55949-57:
(7*5)+(6*5)+(5*9)+(4*4)+(3*9)+(2*5)+(1*7)=170
170 % 10 = 0
So 55949-57-0 is a valid CAS Registry Number.

A DIRECT SYNTHESIS OF 1-CYCLOALKENYLPHOSPHONATES
Banerjee, Shyamal,Engel, Robert,Axelrad, George
, p. 15 - 18 (2007/10/02)
A series of 1-cycloalkenylphosphonoate diesters has been synthesized starting with the corresponding vinylic chlorides.This has been accomplished using the Cu(I) complexes of triethyl phosphite in a direct reaction with the vinylic chlorides.This represen
