6278-69-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6278-69-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,7 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6278-69:
(6*6)+(5*2)+(4*7)+(3*8)+(2*6)+(1*9)=119
119 % 10 = 9
So 6278-69-9 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
