Check Digit Verification of cas no

The CAS Registry Mumber 1415662-51-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,5,6,6 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1415662-51:
(9*1)+(8*4)+(7*1)+(6*5)+(5*6)+(4*6)+(3*2)+(2*5)+(1*1)=149
149 % 10 = 9
So 1415662-51-9 is a valid CAS Registry Number.

Total syntheses of mitragynine, paynantheine and speciogynine via an enantioselective thiourea-catalysed Pictet-Spengler reaction

Kerschgens, Isabel P.,Claveau, Elise,Wanner, Martin J.,Ingemann, Steen,Van Maarseveen, Jan H.,Hiemstra, Henk

, p. 12243 - 12245 (2012)

The pharmacologically interesting indole alkaloids (-)-mitragynine, (+)-paynantheine and (+)-speciogynine were synthesised in nine steps from 4-methoxytryptamine by a route featuring (i) an enantioselective thiourea-catalysed Pictet-Spengler reaction, providing the tetrahydro-β- carboline ring and (ii) a Pd-catalysed Tsuji-Trost allylic alkylation, closing the D-ring.
