145412-04-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145412-04-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,4,1 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 145412-04:
(8*1)+(7*4)+(6*5)+(5*4)+(4*1)+(3*2)+(2*0)+(1*4)=100
100 % 10 = 0
So 145412-04-0 is a valid CAS Registry Number.

Synthesis and Stereochemistry of Spiropyrazolines
Toth, Gabor,Szoelloesy, Aron,Levai, Albert,Kotovych, George
, p. 1895 - 1898 (1986)
Spiropyrazolines have been synthesized by 1,3-dipolar cycloaddition of an 2-arylidene-1-tetralone, 3-arylidene-chromanones, -1-thiochromanones, and -flavanones with diazomethane.The relative configuration and stereochemistry of the products have been dete
