Check Digit Verification of cas no
The CAS Registry Mumber 933454-80-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,3,4,5 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 933454-80:
(8*9)+(7*3)+(6*3)+(5*4)+(4*5)+(3*4)+(2*8)+(1*0)=179
179 % 10 = 9
So 933454-80-9 is a valid CAS Registry Number.

A novel method for the synthesis of 1,3,4-trisubstituted pyrazoles from α-(1,3-dithian-2-yl) enamine ketones and primary amines, involving copper(II)-catalyzed oxidative N-N coupling, has been developed. This unprecedented [4+1] approach is versatile in the synthesis of N-aryl, N-benzyl and N-alkyl pyrazoles, and provides an alternative to the conventional [3+2] methods.
