Check Digit Verification of cas no

The CAS Registry Mumber 944130-10-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,4,1,3 and 0 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 944130-10:
(8*9)+(7*4)+(6*4)+(5*1)+(4*3)+(3*0)+(2*1)+(1*0)=143
143 % 10 = 3
So 944130-10-3 is a valid CAS Registry Number.

Enantioselective total synthesis of phomallenic acid C

Jian, Ya-Jun,Tang, Chao-Jun,Wu, Yikang

, p. 4851 - 4855 (2008/02/05)

(Chemical Equation Presented) The newly isolated bacterial FAS II inhibitor phomallenic acid C (3) was synthesized for the first time as a 16:1 mixture of the (R)- and (S)-isomer with the diyne-allene motif constructed using a coupling under Negishi conditions. By comparison with the synthetic sample, the natural phomallenic acid C was estimated to be a 3.8:1 mixture of (R)-/(S)-isomers. This synthesis describes a new synthetic entry to optically active allene diynes.
