Check Digit Verification of cas no

The CAS Registry Mumber 133942-57-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,9,4 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 133942-57:
(8*1)+(7*3)+(6*3)+(5*9)+(4*4)+(3*2)+(2*5)+(1*7)=131
131 % 10 = 1
So 133942-57-1 is a valid CAS Registry Number.

Regio- and Stereoselective 1,3-Dipolar Cycloaddition of Arylnitrile Oxides to 5-Acetoxy-2(5H)-furanone

Oravec, Peter,Fisera, Lubor,Gazo, Roman

, p. 165 - 170 (2007/10/02)

Arylnitrile oxides undergo regio- and stereo-specific 1,3-dipolar cycloaddition reactions with 5-acetoxy-2(5H)-furanone.In each case a single product 3a-3g results from an anti approach to the 5-acetoxy substituent, the oxygen of the 1,3-dipole being atta
