Check Digit Verification of cas no

The CAS Registry Mumber 334832-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,4,8,3 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 334832-22:
(8*3)+(7*3)+(6*4)+(5*8)+(4*3)+(3*2)+(2*2)+(1*2)=133
133 % 10 = 3
So 334832-22-3 is a valid CAS Registry Number.

Useful synthesis of the main dehydrohexapeptide segment of a macrocyclic antibiotic, berninamycin B

Yamada, Takahiro,Okumura, Kazuo,Yonezawa, Yasuchika,Shin, Chung-Gi

, p. 102 - 103 (2007/10/03)

The useful synthesis of tetradehydrohexapeptide segment 2, which is the main skeleton of a macrocyclic antibiotic, berninamycin B, was first achieved. The skeleton 2 is constructed, in turn, of 2-[(Z)-1-amino-1-propenyl]-5-methyl-oxazole-4-carboxylic acid, α-dehydroalanine (ΔAla), L-Val, 2-[1-amino-1-ethenyl]-5-methyloxazole-4-carboxylic acid residues, besides L-Thr and ΔAla at the N- and C-termini, respectively.
