94491-43-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 94491-43-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,4,9 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 94491-43:
(7*9)+(6*4)+(5*4)+(4*9)+(3*1)+(2*4)+(1*3)=157
157 % 10 = 7
So 94491-43-7 is a valid CAS Registry Number.

INDOLE-2,3-QUINODIMETHANES. SYNTHESIS OF SELECTIVELY PROTECTED DERIVATIVES OF THE FUSED DIMERIC INDOLE ALKALOID STAUROSPORINONE
Magnus, Philip D.,Sear, Nancy L.
, p. 2795 - 2798 (2007/10/02)
The imine 1 was converted via an indole-2,3-quinodimethane cyclization to the hexahydroindolocarbazole 7, which was further converted to the N-carbomethoxy derivative of staurosporinone 2.
