33140-59-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 33140-59-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,1,4 and 0 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 33140-59:
(7*3)+(6*3)+(5*1)+(4*4)+(3*0)+(2*5)+(1*9)=79
79 % 10 = 9
So 33140-59-9 is a valid CAS Registry Number.

Towards the cis-bromination of double bonds

Carman,Derbyshire,Hansford,Kadirvelraj,Robinson

, p. 117 - 126 (2007/10/03)

The bromination of olefins yielding a trans-1,2-dibromo-product was studied. Reagents were proposed to brominate the double bonds of cis-olefins mildly and stereospecifically. Reagents delivering two bromine atoms to the same side of olefins through a cyclic six-membered transition state were studied.
