Check Digit Verification of cas no

The CAS Registry Mumber 688743-60-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,8,7,4 and 3 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 688743-60:
(8*6)+(7*8)+(6*8)+(5*7)+(4*4)+(3*3)+(2*6)+(1*0)=224
224 % 10 = 4
So 688743-60-4 is a valid CAS Registry Number.

Synthesis of novel 11-desmethyl analogues of laulimalide by Nozaki-Kishi coupling

Paterson, Ian,Bergmann, Hermann,Menche, Dirk,Berkessel, Albrecht

, p. 1293 - 1295 (2007/10/03)

As a first entry into structurally simplified analogues of the anticancer agent laulimalide, 11-desmethyl compounds 2 and 3 were selected by molecular modeling. The unfavorable diastereoselectivity in the key synthetic step, a Nozaki-Kishi coupling betwee
