Check Digit Verification of cas no

The CAS Registry Mumber 1018451-70-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,8,4,5 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1018451-70:
(9*1)+(8*0)+(7*1)+(6*8)+(5*4)+(4*5)+(3*1)+(2*7)+(1*0)=121
121 % 10 = 1
So 1018451-70-1 is a valid CAS Registry Number.

Synthesis of fused 4,5-disubstituted indole ring systems by intramolecular friedel-crafts acylation of 4-substituted indoles

Fillion, Eric,Dumas, Aaron M.

, p. 2920 - 2923 (2008/09/19)

(Chemical Equation Presented) 4-Substituted indoles containing a variety of electrophiles and N-substituents undergo Friedel-Crafts acylation to give exclusively the products of cyclization at the 5-position of indole. These indanones and tetralones have been scarcely prepared and are subunits in natural products and analogues of potential biological significance.
