Check Digit Verification of cas no

The CAS Registry Mumber 1440534-70-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,0,5,3 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1440534-70:
(9*1)+(8*4)+(7*4)+(6*0)+(5*5)+(4*3)+(3*4)+(2*7)+(1*0)=132
132 % 10 = 2
So 1440534-70-2 is a valid CAS Registry Number.

Formal total synthesis of lactimidomycin

Nagasawa, Tomohiro,Kuwahara, Shigefumi

supporting information, p. 3002 - 3005 (2013/07/26)

A concise synthesis of an intermediate of lactimidomycin, a glutarimide-containing macrocyclic polyketide produced by an actinomycete, has been accomplished in 35% overall yield from a known vinylketene silyl N,O-acetal by a 10-step sequence that involves two types of asymmetric aldol reactions to install all the stereocenters, the Stille coupling to set up the whole carbon famework, and the Yamaguchi lactonization to construct the 12-membered macrolactone ring.
