Flammability and Explosibility
Notclassified
Check Digit Verification of cas no
The CAS Registry Mumber 645-35-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 5 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 645-35:
(5*6)+(4*4)+(3*5)+(2*3)+(1*5)=72
72 % 10 = 2
So 645-35-2 is a valid CAS Registry Number.

This paper presents the results of our calculations on the geometric parameters, vibrational spectra and hyperpolarizability of a non-linear optical material l-histidine chloride monohydrate. Due to the lack of sufficiently precise information on geometri
Resolution of DL-racemic mixtures

The present invention relates to a process for the resolution of DL-racemic mixtures of compounds which crystalize in the form of a conglumerate. Both, the D and L-enantiomers are obtained according to the invention in a industrially feasable process by adding chiral enantioselective polymers to the supersaturated solution of the racemat to inhibit crystalization of one enantiomer. Next a DL-racemic mixture of said compound is suspended in about twice the amount of the crystallized enantiomer. Consequently, the opposite enantiomer could be recovered by said suspension by physical separation.
