765252-40-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 765252-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,6,5,2,5 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 765252-40:
(8*7)+(7*6)+(6*5)+(5*2)+(4*5)+(3*2)+(2*4)+(1*0)=172
172 % 10 = 2
So 765252-40-2 is a valid CAS Registry Number.

Synthesis of 5-substituted indole derivatives, I. An improved method for the synthesis of sumatriptan

Pete, Bela,Bitter, Istvan,Szantay Jr., Csaba,Schon, Istvan,Toke, Laszlo

, p. 1139 - 1149 (1998)

An improved synthesis of sumatriptan (1b) via Fischer cyclization was achieved by introducing the ethoxycarbonyl group on the N-atom of the sulphonamide moiety in N-methyl-4-hydrazinobenzenemethanesulphonamide (7). As a result, substitution on the benzylic carbon of the indole nucleus could be avoided; however, formation of 1,1-bis-(indol-2-yl)-4-dimethylaminobutane-type by-product (19) was observed. The indolization procedure was optimized to suppress the unwanted side reaction. The N-protection of the sulphonamide moiety was found to be beneficial regarding the purification of the 3-[2-(dimethylamino)ethyl]-N-ethoxycarbonyl-N-methyl-1H-indole-5- methanesulphonamide (18).
