Check Digit Verification of cas no
The CAS Registry Mumber 133146-04-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,1,4 and 6 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 133146-04:
(8*1)+(7*3)+(6*3)+(5*1)+(4*4)+(3*6)+(2*0)+(1*4)=90
90 % 10 = 0
So 133146-04-0 is a valid CAS Registry Number.

SYNTHESIS OF THE NECINE BASE PLATYNECINE FROM GLUCOSE
Fleet, George W.,Seijas, Julio A.,Vazquez-Tato, M. Pilar
, p. 525 - 530 (1991)
A synthesis of platynecine from an intermediate is described which has previously been used for the synthesis of the enantiomers of retronecine; the stereochemistry of the necine base is determined by the formation of a tricyclic amide intermediate.
