130966-65-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130966-65-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,9,6 and 6 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 130966-65:
(8*1)+(7*3)+(6*0)+(5*9)+(4*6)+(3*6)+(2*6)+(1*5)=133
133 % 10 = 3
So 130966-65-3 is a valid CAS Registry Number.

A Practical Synthesis of 2-Carbonylbenzothiophenes
Hsiao, Chi-Nung,Bhagavatula, Lakshmi,Pariza, Richard J.
, p. 1687 - 1695 (2007/10/02)
2-Mercaptobenzoic acid was reduced, alkylated on sulfur atom with various α-halocarbonyl derivatives and then oxidized to 2-thioalkoxybenzaldehydes which underwent intramolecular condensation to give 2-carbonylbenzothiophenes in good yields.
