Check Digit Verification of cas no

The CAS Registry Mumber 1304777-45-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,4,7,7 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1304777-45:
(9*1)+(8*3)+(7*0)+(6*4)+(5*7)+(4*7)+(3*7)+(2*4)+(1*5)=154
154 % 10 = 4
So 1304777-45-4 is a valid CAS Registry Number.

Synthesis of new biheterocycles by a one-pot sonogashira coupling reaction

Deodhar, Mandar,Black, David Stc.,Kumar, Naresh

experimental part, p. 1489 - 1501 (2011/05/14)

Halogenated flavones, isoflavones and indoles were subjected to a one-pot Sonogashira coupling reaction to generate a series of new biheterocyclic compounds. The methodology can be readily adapted to the synthesis of a wide variety of substituted biheterocycles. The Japan Institute of Heterocyclic Chemistry.
