The CAS Registry Mumber 107291-79-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,2,9 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 107291-79:
(8*1)+(7*0)+(6*7)+(5*2)+(4*9)+(3*1)+(2*7)+(1*9)=122
122 % 10 = 2
So 107291-79-2 is a valid CAS Registry Number.

Lewis-acid Promoted Aromatic Cyclization of &α-Chlorosulfides: Synthesis of Ethyl Isothiochroman-1-carboxylate and Related Compounds

Ishibashi, Hiroyuki,Okada, Motofumi,Iida, Kyoko,Ikeda, Masazumi

, p. 1527 - 1529 (2007/10/02)

A variety of ethyl isothiochroman-1-carboxylates and related compounds were synthesized by treatment of 2-chloro-2-acetates with stannic chloride in methylene chloride.The same procedure was applied to the synthesis of ethyl 4-chloro-4-methyltetrahydrothiopyran-2-carboxylate.Some isothiochroman-1-carboxylic acids were prepared and evaluated for antiinflammatory activity.Among the compounds tested, 7-phenoxyisothiochroman-1-carboxylic acid showed weak activity.
