Check Digit Verification of cas no

The CAS Registry Mumber 153654-26-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,6,5 and 4 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 153654-26:
(8*1)+(7*5)+(6*3)+(5*6)+(4*5)+(3*4)+(2*2)+(1*6)=133
133 % 10 = 3
So 153654-26-3 is a valid CAS Registry Number.

Synthesis of 5-substituted indole derivatives, part II. Synthesis of sumatriptan through the Japp-Klingemann reaction

Pete, Bela,Bitter, Istvan,Harsanyi, Kalman,Toke, Laszlo

, p. 665 - 673 (2007/10/03)

Synthesis of selective 5-HT(1B/1D) receptor agonist, sumatriptan (1) was accomplished through decarboxylation of 2-carboxy-3-[2-(dimethylamino)ethyl]- N-methyl-1H-indole-5-methanesulfonamide (2) in quinoline with copper powder. The preparation of the acid (2) was effected through the Japp-Klingemann method thus avoiding the need for the formation of hydrazine from diazonium salt. Attempted decarboxylation in N,N-dimethylacetamide resulted in the formation of the β-carboline (16).
