130423-56-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130423-56-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,4,2 and 3 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 130423-56:
(8*1)+(7*3)+(6*0)+(5*4)+(4*2)+(3*3)+(2*5)+(1*6)=82
82 % 10 = 2
So 130423-56-2 is a valid CAS Registry Number.

SYNTHESIS OF FUNCTIONALLY SUBSTITUTED BENZOPYRYLIUM SALTS
Nikolyukin, Yu. A.,Bogza, S. L.,Dulenko, V. I.
, p. 397 - 402 (2007/10/02)
Benzopyrylium salts that contain an acetyl, cyano, or ethoxycarbonyl group in the 4 position of the pyrylium ring were synthesized by the reaction of 3-(3,4-dimethoxyphenyl)pentane-2,4-dione and α-(3,4-dimethoxyphenyl)acetoacetonitrile and ethyl α-(3,4
