Check Digit Verification of cas no

The CAS Registry Mumber 163929-90-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,9,2 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 163929-90:
(8*1)+(7*6)+(6*3)+(5*9)+(4*2)+(3*9)+(2*9)+(1*0)=166
166 % 10 = 6
So 163929-90-6 is a valid CAS Registry Number.

Synthesis of 3-Substituted Pentane-2,4-diones: Valuable Intermediates for Liquid Crystals

Cativiela, Carlos,Serrano, Jose L.,Zurbano, Maria M.

, p. 3074 - 3083 (2007/10/02)

General procedures for the synthesis of six series of 3-substituted pentane-2,4-diones are described.The diones were used as intermediates in the preparation of pyrazoles, isoxazoles, and coordination complexes whose mesogenic properties have been studied.Nematic and smectic phases have been obtained in a number of cases, and relationship between molecular structure and mesogenic properties has been explored.
