136918-52-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136918-52-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,9,1 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 136918-52:
(8*1)+(7*3)+(6*6)+(5*9)+(4*1)+(3*8)+(2*5)+(1*2)=150
150 % 10 = 0
So 136918-52-0 is a valid CAS Registry Number.

A method of synthesizing 2-acetylamino-7-hydroxy-6-phenylthio-3-carbethoxybenzothiophenes from 6-phenylthio-7-oxo-4,5,6,7-tetrahydrobenzothiophenes has been developed.A method is also proposed for synthesis of 7-phenylthiobenzothienopyrimidin
