Check Digit Verification of cas no
The CAS Registry Mumber 178991-19-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,9,9 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 178991-19:
(8*1)+(7*7)+(6*8)+(5*9)+(4*9)+(3*1)+(2*1)+(1*9)=200
200 % 10 = 0
So 178991-19-0 is a valid CAS Registry Number.

A formal synthesis of (-)-pumiliotoxin C
Davies, Stephen G.,Bhalay, Gurdip
, p. 1595 - 1596 (1996)
An asymmetric synthesis of an advanced intermediate in the synthesis of natural (-)-pumiliotoxin C has been achieved in six steps and in 61% overall yield employing as the key step a highly diastereoselective lithium amide 1,4-conjugate addition to a dien
