Check Digit Verification of cas no

The CAS Registry Mumber 92208-77-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,2,0 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 92208-77:
(7*9)+(6*2)+(5*2)+(4*0)+(3*8)+(2*7)+(1*7)=130
130 % 10 = 0
So 92208-77-0 is a valid CAS Registry Number.

Generation of Diastereomeric Cyclopropanes from Benzylidenesulfuranes and Chalcones

Stahl, Ingfried,Schomburg, Sabine,Kalinowski, Hans Otto

, p. 2247 - 2260 (2007/10/02)

The reaction of the benzylidenesulfuranes 2, available by deprotonation of the benzylsulfonium bromides 1, with chalcones 3, which are substituted in the aroyl part, leads to the stereoisomeric cyclopropanes 4 and 5.The stereochemistry of 4 and 5 is elucidated by spectroscopy.A carbenic mechanism of formation of 4 and 5 is excluded experimentally.
