126950-52-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126950-52-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,9,5 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 126950-52:
(8*1)+(7*2)+(6*6)+(5*9)+(4*5)+(3*0)+(2*5)+(1*2)=135
135 % 10 = 5
So 126950-52-5 is a valid CAS Registry Number.

Mechanism of wittig reaction: Evidence against betaine intermediates
Vedejs,Marth
, p. 3905 - 3909 (2007/10/02)
The ratio of oxaphosphetane pseudorotamers 8 and 9 obtained from the Wittig reaction of ylide 7 and hydrocinnamaldehyde has been determined at -95 and -109 °C (conditions where the interconversion of isomers by pseudorotation is slow) to be in the range o
