The CAS Registry Mumber 33830-03-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,8,3 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 33830-03:
(7*3)+(6*3)+(5*8)+(4*3)+(3*0)+(2*0)+(1*3)=94
94 % 10 = 4
So 33830-03-4 is a valid CAS Registry Number.

THERMAL TRANSFORMATIONS OF GEM-DIHALOGENODIPHENYLCYCLOPROPANES

Kostikov, R. R.,Varakin, G. S.,Ogloblin, K. A.

, p. 1438 - 1444 (2007/10/02)

When gem-dihalogenodiphenylcyclopropanes are heated, 2-halogenophenylindenes or diphenyl-2-halogeno-1,3-alkadienes are formed.The yields of the substituted indenes are increased in the presence of acidic catalysts, while the yield of the dienes is increas
