1628-60-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1628-60-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,2 and 8 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1628-60:
(6*1)+(5*6)+(4*2)+(3*8)+(2*6)+(1*0)=80
80 % 10 = 0
So 1628-60-0 is a valid CAS Registry Number.

Synthesis of ethenylbenzothiazole derivatives
Ohba,Kosaka,Wakabayashi
, p. 3421 - 3426 (2007/10/03)
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
