Check Digit Verification of cas no

The CAS Registry Mumber 155687-80-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,6,8 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 155687-80:
(8*1)+(7*5)+(6*5)+(5*6)+(4*8)+(3*7)+(2*8)+(1*0)=172
172 % 10 = 2
So 155687-80-2 is a valid CAS Registry Number.

Benzyl Methyl (S)-2-(p-Tolylsulfinyl)maleate: An Efficient Dienophile for the Enantioselective Synthesis of Cyclohexadienes

Alonso, Ines,Carretero, Juan C.,Ruano, Jose L. Garcia

, p. 3231 - 3232 (2007/10/02)

The new dienophile, benzyl methyl (S)-2-(p-tolylsulfinyl)maleate, readily prepared in two steps from benzyl acetate, reacts with a wide variety of 1,3-dienes, under catalysis by TiCl4, in a very regioselective and stereoselective manner to give optically
