Check Digit Verification of cas no
The CAS Registry Mumber 116171-72-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,1,7 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 116171-72:
(8*1)+(7*1)+(6*6)+(5*1)+(4*7)+(3*1)+(2*7)+(1*2)=103
103 % 10 = 3
So 116171-72-3 is a valid CAS Registry Number.

Coupling of racemic 16-methoxycarbonyl-15,20-dihydro-3,Nb-seco-cleavamine derivative 34 with (-)vindoline via chloroindolenine intermediate 41 occurs with high stereoselectivity and leads after cyclization to the separable dimers 46I and 46II with natural C(14'), C(16')-configuration in good yields.Tetracyclic lactam 37 with vinblastine analogous stereochemistry is prepared and transfomed to chloroindolenine 38.Coupling of 38 with N,N-dimethyl-m-anisidine was achieved in good yield.
