Check Digit Verification of cas no
The CAS Registry Mumber 61892-77-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,8,9 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 61892-77:
(7*6)+(6*1)+(5*8)+(4*9)+(3*2)+(2*7)+(1*7)=151
151 % 10 = 1
So 61892-77-1 is a valid CAS Registry Number.

SYNTHESIS AND MOLECULAR STRUCTURE OF PIPLARTINE (=PIPERLONGUMINE)
Boll, Per M.,Hansen, Jesper,Simonsen, Ole,Thorup, Niels
, p. 171 - 176 (2007/10/02)
The structure of piplartine (=piperlongumine) was established as (E)-N-3',4',5'-trimethoxycinnamoyl-5,6-dihydro-2(1H)-pyridone (13) by synthesis and by an X-ray crystallographic analysis.Model condensation of (E)-3,4,5-trimethoxycinnamoyl chloride and crotonamide gave not the expected ciannamoylcrotonamide, but (E)-N-3',4',5'-trimethoxycinnamoyl-3-chlorobutyramide (12).
