Check Digit Verification of cas no
The CAS Registry Mumber 401-84-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,0 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 401-84:
(5*4)+(4*0)+(3*1)+(2*8)+(1*4)=43
43 % 10 = 3
So 401-84-3 is a valid CAS Registry Number.

The asymmetric bromine-lithium exchange on a series of prochiral biphenyls was investigated. As in many asymmetric organolithium reactions, the chiral ligand (here a diamine) was considered to be the enantiocontrolling element. We show here that the organ
