Check Digit Verification of cas no

The CAS Registry Mumber 74423-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,2 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74423-20:
(7*7)+(6*4)+(5*4)+(4*2)+(3*3)+(2*2)+(1*0)=114
114 % 10 = 4
So 74423-20-4 is a valid CAS Registry Number.

3'-Arylspiro-3-ones and Their Conversion to 2-(3-Arylisoxazol-5-yl)benzoates

Liu, Kou-Chang,Howe, Robert K.

, p. 4590 - 4592 (2007/10/02)

A new, convenient route to the biologically active 2-(3-arylisoxazol-5-yl)benzoates 4 is reported.This route consists of 1,3-dipolar cycloaddition of aromatic nitrile oxides to 3-methylenephthalide to form the novel 3'-arylspiro-3-ones 3 and subsequent high-yield conversions of 3 to 4.
