Check Digit Verification of cas no

The CAS Registry Mumber 126572-48-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,5,7 and 2 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 126572-48:
(8*1)+(7*2)+(6*6)+(5*5)+(4*7)+(3*2)+(2*4)+(1*8)=133
133 % 10 = 3
So 126572-48-3 is a valid CAS Registry Number.

Three Routes to the Critical C16'-C14' Parf Relative Stereochemistry of Vinblastine. Syntheses of 20'-Desethyl-20'-deoxyvinblastine and 20'-Desethyl-20'-deoxyvincovaline

Kuehne, M. E.,Zebovitz, T. C.,Bornmann, W. G.,Marko, I.

, p. 4340 - 4349 (1987)

Coupling reactions of vindoline (2) with the racemic chloro imine derivative 8 of 14-epi-D-secodesethylvincadifformine (7) resulted in a selective high yield formation of the C16'-C14' parf (vinblastine type) relative configuration of the coupling product
