Check Digit Verification of cas no

The CAS Registry Mumber 1031421-19-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,1,4,2 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1031421-19:
(9*1)+(8*0)+(7*3)+(6*1)+(5*4)+(4*2)+(3*1)+(2*1)+(1*9)=78
78 % 10 = 8
So 1031421-19-8 is a valid CAS Registry Number.

Synthetic studies toward the total synthesis of amphidinolide H1

Deng, Lisheng,Ma, Zhixiong,Zhao, Gang

, p. 728 - 732 (2008)

A convergent synthesis of the macrolide core as the immediate precursor to amphidinolide H1 is described, which features a palladium-catalyzed Stille cross-coupling, a methyl ketone diastereoselective aldol reaction, a Mitsunobu esterification, and an intramolecular ring-closing metathesis (RCM) reaction to construct the 26-membered macrocycle as key steps.
