5132-05-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5132-05-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,3 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5132-05:
(6*5)+(5*1)+(4*3)+(3*2)+(2*0)+(1*5)=58
58 % 10 = 8
So 5132-05-8 is a valid CAS Registry Number.

Synthesis of ethenylbenzothiazole derivatives
Ohba,Kosaka,Wakabayashi
, p. 3421 - 3426 (1995)
Ethenylbenzothiazoles were synthesized by the Horner-Emmons reaction of benzothiazolylmethylphosphonate with aldehydes under phase transfer catalytic conditions in 60-71% yields. Not only aromatic but also aliphatic aldehydes gave the desired products und
