Check Digit Verification of cas no

The CAS Registry Mumber 1264292-59-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,4,2,9 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1264292-59:
(9*1)+(8*2)+(7*6)+(6*4)+(5*2)+(4*9)+(3*2)+(2*5)+(1*9)=162
162 % 10 = 2
So 1264292-59-2 is a valid CAS Registry Number.

Synthesis of coumarin-substituted thiazolyl-pyrazolone derivatives via one-pot reaction

Chunduru, Venkata S. R.,Rao, Vedula Rajeswar

, p. 545 - 550 (2011/08/07)

An efficient multi-component reaction for the preparation of 4-arylidene-3-methyl-1-4-[2-oxo-2H-chromen-3-yl)thiazol-2-yl]-1H-pyrazol-5(4H) -ones 5 has been described. The synthesis process involves the simultaneous formation of two heterocycles such as thiazole and pyrazolone along with the condensation of an active methylene group by aldehydes via the Knoevenagel reaction.
