Check Digit Verification of cas no

The CAS Registry Mumber 837416-53-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,3,7,4,1 and 6 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 837416-53:
(8*8)+(7*3)+(6*7)+(5*4)+(4*1)+(3*6)+(2*5)+(1*3)=182
182 % 10 = 2
So 837416-53-2 is a valid CAS Registry Number.

Synthesis and characterisation of some 2-[2(1-phenyl-3-thiophen-2-yl-1H- pyrazol-4-yl)]-vinyl chromene-4-ones

Joshi,Karale,Gill

, p. 307 - 312 (2007/10/03)

β-Diketone 5 is prepared by BakerVenkatram'an transformation of the ester 4, which is obtained by esterification of the acrylic acid 2 with 2-hydroxyacetophenone 3. The acid catalyzed cyclization of 5 yielded 2-[2(1-phenyl-3-thiophen-2-yl-1H-pyrazol-4-yl)
