Check Digit Verification of cas no
The CAS Registry Mumber 138535-41-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,5,3 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 138535-41:
(8*1)+(7*3)+(6*8)+(5*5)+(4*3)+(3*5)+(2*4)+(1*1)=138
138 % 10 = 8
So 138535-41-8 is a valid CAS Registry Number.

Efficient total synthesis of AI-77-B, a gastroprotective substance from Bacillus pumilus AI-77
Hamada,Hara,Kawai,Kohno,Shioiri
, p. 8635 - 8652 (2007/10/02)
First total synthesis of AI-77-B (1), a gastroprotective substance from Bacillus pumilus AI-77, was achieved in a stereoselective and convergent manner. In this synthesis, the dihydroisocoumarin part 2 was constructed in one step through 1,2-addition of the benzylic anion 17b to Boc-L-leucinal 7b. The hydroxy amino acid 4 was elaborated from (R)-glutamic acid in a highly stereoselective manner. Condensation of 2·HCl and 4, intramolecular Pinner reaction, followed by mild hydrolysis afforded AI-77-B (1).
