Check Digit Verification of cas no

The CAS Registry Mumber 74767-41-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,6 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74767-41:
(7*7)+(6*4)+(5*7)+(4*6)+(3*7)+(2*4)+(1*1)=162
162 % 10 = 2
So 74767-41-2 is a valid CAS Registry Number.

Thiophene Ring Annelation: Part IV - Synthesis of 2-Iodo-7-(p-tolyl)-benzothiophene and 2-Iodo-4(H)-oxo-6-(p-tolyl)cyclopentathiophene-5-carboxamide

Moussa, H. H.,Haggag, B.

, p. 156 - 157 (2007/10/02)

p-Tolyl 2-iodo-4-thienyl ketone (I) undergoes condensation with dimethyl succinate in the presence of potassium t-butoxide to give predominantly the trans(SC4H2I/CO2Me)-acid ester (IIa) which is converted into benzothiophene derivatives (IIIa and IIIb).Ketone (I) when allowed to react with malononitrile yields α-cyano-β-(2-iodo-4-thienyl)-β-(p-tolyl)acrylonitrile (IV) which undergoes cyclization in conc. sulphuric acid to give 2-iodo-4(H)-oxo-6-(p-tolyl)cyclopentathiophene-5-carboxamide (V) along with α-carbamyl-β-(2-iodo-4-thienyl)-β-(p-tolyl)acrylonitrile (VI).
