Calculate Digit Verification of CAS Registry Number 201531-95:
(8*2)+(7*0)+(6*1)+(5*5)+(4*3)+(3*1)+(2*9)+(1*5)=85
85 % 10 = 5
So 201531-95-5 is a valid CAS Registry Number.

Synthesis of amides from Glycosmis species: Methylthiopropenoic acid, methylsulfonylpropenoic acid, thiocarbamic acid S-methyl ester, and senecioic acid amides

Hinterberger, Sabine,Hofer, Otmar,Greger, Harald

, p. 487 - 496 (1998)

Representative samples of several types of naturally occurring amides from south and southeast Asian Glycosmis species were synthesized for proof of structures and for bioactivity testing. With one exception (senecioic acid) all these amides were characterized by sulfur containing acid components (methylthiopropenoic acid, methylsulfonylpropenoic acid, and thiocarbamic acid) in combination with phenethylamine derived amino moieties.
