Check Digit Verification of cas no
The CAS Registry Mumber 54764-57-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,7,6 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 54764-57:
(7*5)+(6*4)+(5*7)+(4*6)+(3*4)+(2*5)+(1*7)=147
147 % 10 = 7
So 54764-57-7 is a valid CAS Registry Number.

CYCLOPROPANE FORMATION FROM 4,5-UNSATURATED THIOPHENYLETHERS. CONVERSION OF LIMONENE INTO CAR-2-ENE
Fourneron, J. D.,Harwood, L. M.,Julia, M.
, p. 693 - 696 (2007/10/02)
Strong bases can abstract a proton α to a double bond.A phenylthio group γ to that double bond can be eliminated at the same time leading to a cyclopropane ring.The procedure is illustrated by a conversion of limonene into car-2-ene.
