1296134-68-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1296134-68-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,6,1,3 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1296134-68:
(9*1)+(8*2)+(7*9)+(6*6)+(5*1)+(4*3)+(3*4)+(2*6)+(1*8)=173
173 % 10 = 3
So 1296134-68-3 is a valid CAS Registry Number.

Synthesis and biological evaluation of coumarinyl sydnone derivatives
Patel, Keshav C.,Patel, Himanshu D.
, p. 113 - 118 (2012/02/03)
A novel series of compounds containing coumarinyl sydnone derivatives from 4-methyl-7-hydroxy-8-nitro coumarin were synthesized. The formed compounds have been evaluated by physical methods (melting point, thin layer chromatography, elemental analysis) an
