Check Digit Verification of cas no

The CAS Registry Mumber 1236074-94-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,6,0,7 and 4 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1236074-94:
(9*1)+(8*2)+(7*3)+(6*6)+(5*0)+(4*7)+(3*4)+(2*9)+(1*4)=144
144 % 10 = 4
So 1236074-94-4 is a valid CAS Registry Number.

Total Synthesis and Stereochemical Revision of the Anti-Tuberculosis Peptaibol Trichoderin A

Kavianinia, Iman,Kunalingam, Lavanya,Harris, Paul W. R.,Cook, Gregory M.,Brimble, Margaret A.

, p. 3878 - 3881 (2016)

The first total synthesis of the postulated structure of the aminolipopeptide trichoderin A and its epimer are reported. A late-stage solution phase C-terminal coupling was employed to introduce the C-terminal aminoalcohol moiety. This methodology provides a foundation to prepare analogues of trichoderin A to establish a structure-activity relationship. NMR spectroscopic analysis established that the C-6 position of the 2-amino-6-hydroxy-4-methyl-8-oxodecanoic acid (AHMOD) residue in trichoderin A possesses an (R)-configuration as opposed to the originally proposed (S)-configuration.
