The CAS Registry Mumber 93041-19-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,0,4 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 93041-19:
(7*9)+(6*3)+(5*0)+(4*4)+(3*1)+(2*1)+(1*9)=111
111 % 10 = 1
So 93041-19-1 is a valid CAS Registry Number.

Nucleophile singulett-carbene in der inversen [4+]-cycloaddition: Eine neue isopyrazol-synthese

Kuemmeil, Andreas,Seitz, Guenther

, p. 2743 - 2746 (2007/10/02)

Dimethoxycarbene, generated from the norbornadienone ketal 6 or from triethyl orthoformate 12a can be trapped by various 1,2,4,5-tetrazines 1 to yield the corresponding isopyrazoles 10 in high yields via [4+1]-cycloaddition followed by [4+2]-cycloreversio
