Check Digit Verification of cas no

The CAS Registry Mumber 55239-18-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,2,3 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 55239-18:
(7*5)+(6*5)+(5*2)+(4*3)+(3*9)+(2*1)+(1*8)=124
124 % 10 = 4
So 55239-18-4 is a valid CAS Registry Number.

Enantioselective synthesis of tertiary thiols by intramolecular arylation of lithiated thiocarbamates

MacLellan, Paul,Clayden, Jonathan

supporting information; experimental part, p. 3395 - 3397 (2011/05/04)

Lithiation of N-aryl S-α-alkylbenzyl thiocarbamates leads to rearrangement with migration of the N-aryl ring to the anionic centre α to S, a process which generally proceeds with ca. 98% retention of stereochemistry and returns chiral benzylic tertiary thiols in high enantiomeric ratios.
