Check Digit Verification of cas no

The CAS Registry Mumber 102960-87-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,9,6 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 102960-87:
(8*1)+(7*0)+(6*2)+(5*9)+(4*6)+(3*0)+(2*8)+(1*7)=112
112 % 10 = 2
So 102960-87-2 is a valid CAS Registry Number.

Synthesis and pharmacology of N-isomeric quaternary tropane compounds

Nador,Scheiber,Karpati,Grober

, p. 1324 - 1327 (2007/10/02)

The synthesis of (8r)-8-(4-biphenylmethyl)-atropinium bromide (3) as N-isomeric form of xenytropium bromide, (8s)-8-(4-biphenylmethyl)-atropinium bromide (2), is reported. It was revealed, that the equatorial alkylation predominates in quaternization of tertiary tropane compounds. Furthermore, the preparation of other N-isomeric pairs of quaternary tropane derivatives in pure form is described. Xenytropium bromide is more active - 16 times on the parasympathetic end-plate and 8 times on the ganglion - than its N-isomer.
