Check Digit Verification of cas no

The CAS Registry Mumber 69841-48-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,8,4 and 1 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 69841-48:
(7*6)+(6*9)+(5*8)+(4*4)+(3*1)+(2*4)+(1*8)=171
171 % 10 = 1
So 69841-48-1 is a valid CAS Registry Number.

Stereochemistry. Part 62: Acetolysis of Triterpenoid p-Toluenesulfonates. Part 2

Audouin, Max,Cortez, Julia Bocanegra de,Hamon, Louis,Levisalles, Jacques,Platzer, Nicole

, p. 5287 - 5304 (1998)

Synthesis of p-toluenesulfonates 8b and 9b and of labelled analogs is described and previous assignements of proton NMR signals for quaternary methyl groups are confirmed. Acetolysis of these p-toluenesulfonates in the presence of NaOAc gave both substitution and elimination products. Substitution could be accounted for by bimolecular processes (SN2 on carbon, SAN on sulfur). Kinetics confirmed the intervention of bimolecular processes for 8b. Elimination products came for a great part from intermediates formed by hydride and/or methyl shifts. All rearranged products could be explained by plain sigmatropic rearrangements or by contact ion pair rearrangements. Attention is drawn to the close resemblance between sigmatropic rearrangements and contact ion pair rearrangements.
