155687-88-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 155687-88-0 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 8 respectively.
Calculate Digit Verification of CAS Registry Number 155687-88:
(8*1)+(7*5)+(6*5)+(5*6)+(4*8)+(3*7)+(2*8)+(1*8)=180
180 % 10 = 0
So 155687-88-0 is a valid CAS Registry Number.

Benzyl Methyl (S)-2-(p-Tolylsulfinyl)maleate, an Efficient Dienophile in Asymmetric Diels-Alder Reactions
Alonso, Ines,Carretero, Juan C.,Ruano, Jose L. Garcia
, p. 1499 - 1508 (2007/10/02)
The enantiomerically pure dienophile 3 was readily prepared in a three-step sequence from benzyl acetate and (-)-(S)-menthyl p-toluenesulfinate (46percent overall yield).This vinyl sulfoxide reacted in high
