Check Digit Verification of cas no

The CAS Registry Mumber 943975-95-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,3,9,7 and 5 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 943975-95:
(8*9)+(7*4)+(6*3)+(5*9)+(4*7)+(3*5)+(2*9)+(1*5)=229
229 % 10 = 9
So 943975-95-9 is a valid CAS Registry Number.

Synthesis of DEFG ring of complestatin and chloropeptin I: Highly atropdiastereoselective macrocyclization by intramolecular Suzuki-Miyaura reaction

Jia, Yanxing,Bois-Choussy, Michele,Zhu, Jieping

, p. 2401 - 2404 (2007)

Palladium-catalyzed intramolecular Suzuki-Miyaura reaction of linear tripeptide (23) afforded the 16-membered DEFG ring of complestatin (3) in good yield with an excellent atropdiastereoselectivity. Acidic treatment of 3 triggers a stereospecific rearrang
