Check Digit Verification of cas no

The CAS Registry Mumber 1384524-22-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,4,5,2 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1384524-22:
(9*1)+(8*3)+(7*8)+(6*4)+(5*5)+(4*2)+(3*4)+(2*2)+(1*2)=164
164 % 10 = 4
So 1384524-22-4 is a valid CAS Registry Number.

Synthesis of a new chiral sulfonic acid

Das, Joydeb,Le Cavelier, Fabien,Rouden, Jacques,Blanchet, Jermoe

, p. 1349 - 1352 (2012)

A convenient route to an original chiral sulfonic acid is disclosed. The synthesis is based on an optimized and regioselective direct bis-orthoarylation of a commercially available phenol, followed by a Newman-Kwart rearrangement. Resolution by preparative chiral HPLC and oxidative cleavage give the targeted Brnsted acid in >99% ee. Georg Thieme Verlag Stuttgart · New York.
