637778-81-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 637778-81-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,7,7,7 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 637778-81:
(8*6)+(7*3)+(6*7)+(5*7)+(4*7)+(3*8)+(2*8)+(1*1)=215
215 % 10 = 5
So 637778-81-5 is a valid CAS Registry Number.

Isolation and Structure Determination of Lyngbyastatin 3, a Lyngbyastatin 1 Homologue from the Marine Cyanobacterium Lyngbya majuscula. Determination of the Configuration of the 4-Amino-2,2-dimethyl-3-oxopentanoic Acid Unit in Majusculamide C, Dolastatin 12, Lyngbyastatin 1, and Lyngbyastatin 3 from Cyanobacteria

Williams, Philip G.,Moore, Richard E.,Paul, Valerie J.

, p. 1356 - 1363 (2003)

The structure of lyngbyastatin 3 (1), including the configurations of the two unusual amino acid residues, viz., the 3-amino-2-methylhexanoic acid (Amha) and 4-amino-2,2-dimethyl-3-oxopentanoic acid units (Ibu), has been established by chemical degradation. Analysis of the cyanobacterial samples of lyngbyastatin 3 (1), lyngbyastatin 1 (2), and dolastatin 12 (3) demonstrated that they are mixtures of Ibu epimers [R (major) and S (minor)], whereas the structurally related majusculamide C (4) is a single diastereomer having an S-Ibu unit.
