Butanedioic acid, (1-methylethyl)-, (S)-, also known as (S)-2-methylbutanedioic acid or (S)-2-methylsuccinic acid, is a chiral organic compound with the molecular formula C6H10O4. It is a dicarboxylic acid, meaning it contains two carboxylic acid groups, and is a derivative of butanedioic acid (succinic acid) with a methyl group attached to the second carbon atom. The (S)-enantiomer indicates that the molecule has a specific three-dimensional arrangement, with the methyl group on the left side when looking at the molecule from the perspective of the carboxylic acid group. Butanedioic acid, (1-methylethyl)-, (S)- is used in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals due to its unique chiral properties and reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 1187-70-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,8 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1187-70:
(6*1)+(5*1)+(4*8)+(3*7)+(2*7)+(1*0)=78
78 % 10 = 8
So 1187-70-8 is a valid CAS Registry Number.

Two novel cyclic depsipeptides, ulleungamides A (1) and B (2), were isolated from cultures of terrestrial Streptomyces sp. Their structures were determined by analyses of spectroscopic data and various chemical transformations, including modified Mosher's method, advanced Marfey's method, PGME, GITC derivatizations, and Snatzke's method. Ulleungamides were determined to be a new class of peptides bearing unprecedented units, such as 5-hydroxy-6-methyl-2,3-dehydropipecolic acid, 4,5-dihydroxy-6-methyl-2,3-dehydropipecolic acid, and amino-linked 2-isopropylsuccinic acid. Ulleungamide A displayed growth inhibitory activity against Staphylococcus aureus and Salmonella typhimurium without cytotoxicity.
