Check Digit Verification of cas no
The CAS Registry Mumber 425394-71-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,5,3,9 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 425394-71:
(8*4)+(7*2)+(6*5)+(5*3)+(4*9)+(3*4)+(2*7)+(1*1)=154
154 % 10 = 4
So 425394-71-4 is a valid CAS Registry Number.

Condensed thiophenes and selenophenes: Thionyl chloride and selenium oxychloride as sulfur and selenium transfer reagents

3,4-Cyanomethyl substituted thiophenes reacted with thionyl chloride in the presence of base to give dicyano substituted thieno(3,4-c)thiophenes. The use of selenium oxychloride furnished the corresponding cyano substituted seleno(3,4-c)thiophene. 1,2-Phenylenediacetonitriles gave the corresponding cyano substituted benzo(c)thiophenes and benzo(c)selenenophenes, respectively, upon reaction with thionyl chloride and selenium oxychloride in the presence of base.
