Check Digit Verification of cas no
The CAS Registry Mumber 137267-11-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,2,6 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 137267-11:
(8*1)+(7*3)+(6*7)+(5*2)+(4*6)+(3*7)+(2*1)+(1*1)=129
129 % 10 = 9
So 137267-11-9 is a valid CAS Registry Number.

REACTIONS OF 2-AMINOBENZOTHIAZOLES WITH PHENYL GLYCIDYL ETHER
Ambartsumova, R. F.,Kosmacheva, L. P.
, p. 547 - 551 (2007/10/02)
In acidic media 2-aminobenzothiazole and its derivatives react with phenyl glycidyl ether at the ring nitrogen atom, while in alkaline media they react at the exocyclic nitrogen atom.The structures of the compounds were proved by spectral methods and alternative synthesis.
