Check Digit Verification of cas no

The CAS Registry Mumber 108263-92-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,2,6 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 108263-92:
(8*1)+(7*0)+(6*8)+(5*2)+(4*6)+(3*3)+(2*9)+(1*2)=119
119 % 10 = 9
So 108263-92-9 is a valid CAS Registry Number.

OXIDATION OF 1,2,3-BUTATRIENES: A FACILE FORMATION OF METHYLENECYCLOPROPANONES AND THEIR SUBSEQUENT PHOTODECARBOXYLATION

Ando, Wataru,Hayakawa, Hiroshi,Tokitoh, Norihiro

, p. 6357 - 6360 (2007/10/02)

A peracid oxidation of some sterically hindered 1,2,3-butatrienes (4) using an alkaline biphasic solvent system was examined, and the resulted methylenecyclopropanones (5) were readily photodecarboxylated to give the corresponding allenes (6) in good yiel
