137369-18-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137369-18-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,3,6 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 137369-18:
(8*1)+(7*3)+(6*7)+(5*3)+(4*6)+(3*9)+(2*1)+(1*8)=147
147 % 10 = 7
So 137369-18-7 is a valid CAS Registry Number.

Protonation Studies on the Oximes of Some 7-Acetyl-1,2-benzoisothiazoles
McKinnon, David M.,Abouzeid, Azza A.
, p. 1193 - 1196 (2007/10/02)
Three 7-acetyl-1,2-benzoisothiazoles have been made by cyclisation of the monooximes of 2-methylthio-1,3-diacetylbenzenes.The oximes of these ketones dissolved in acidic media give only protonated forms, and no indication of the formation of stable bridge
