Check Digit Verification of cas no

The CAS Registry Mumber 136339-45-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,3,3 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 136339-45:
(8*1)+(7*3)+(6*6)+(5*3)+(4*3)+(3*9)+(2*4)+(1*5)=132
132 % 10 = 2
So 136339-45-2 is a valid CAS Registry Number.

The synthesis of polyunsaturated α,ω-dicarboxylic acids. I. Chemical synthesis of octadecadienedioic acids regioisomeric in double bond positions

Ivanov,Groza,Mal'chenko,Myagkova,Shewe

, p. 481 - 487 (2007/10/03)

Novel compounds, (6Z,9Z)-octadecadienedioic acid, its regioisomers in double bond positions, and their acetylenic precursors, were synthesized. A general approach to the synthesis of a series of ω-hydroxyacetylenic acids in the context of a unique synthetic scheme was suggested.
