The CAS Registry Mumber 90032-95-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,3 and 2 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 90032-95:
(7*9)+(6*0)+(5*0)+(4*3)+(3*2)+(2*9)+(1*5)=104
104 % 10 = 4
So 90032-95-4 is a valid CAS Registry Number.

THE HIGHLY SELECTIVE REACTION OF LITHIUM DITHIOESTER ENOLATES WITH β-ALKENYL-β-PROPIOLACTONES: A SIMPLE METHOD FOR THE SYNTHESIS OF 6-(METHYLTHIO)THIOCARBONYL-(E)-3-ALKENOIC ACIDS

Fujisawa, Tamotsu,Itoh, Toshiyuki,Sato, Toshio

, p. 1901 - 1904 (1983)

Lithium dithioester enolates were found to react with β-alkenyl-β-propiolactones highly regio- and stereoselectively at the terminal vinyl carbon to give 6-(methylthio)thiocarbonyl-(E)-3-alkenoic acids, masked 1,7-dicarboxylic compounds.
