Check Digit Verification of cas no

The CAS Registry Mumber 199169-54-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,1,6 and 9 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 199169-54:
(8*1)+(7*9)+(6*9)+(5*1)+(4*6)+(3*9)+(2*5)+(1*4)=195
195 % 10 = 5
So 199169-54-5 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.
