Description
A recently discovered alkaloid, ajmalicinine has been obtained from the root bark of
Cabucala striolata. The structure closely resembles that of the preceding base and
has been established by chemical and spectroscopic methods.

Check Digit Verification of cas no
The CAS Registry Mumber 55529-55-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,5,2 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 55529-55:
(7*5)+(6*5)+(5*5)+(4*2)+(3*9)+(2*5)+(1*5)=140
140 % 10 = 0
So 55529-55-0 is a valid CAS Registry Number.
