Check Digit Verification of cas no

The CAS Registry Mumber 62357-54-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,3,5 and 7 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 62357-54:
(7*6)+(6*2)+(5*3)+(4*5)+(3*7)+(2*5)+(1*4)=124
124 % 10 = 4
So 62357-54-4 is a valid CAS Registry Number.

Synthesis and some transformations of (-)-carveol

Valeev,Vostrikov,Miftakhov

experimental part, p. 810 - 814 (2009/12/09)

Reduction of the oxo group in (-)-carvone with LiAlH4, NaBH4, and (i-Bu)2AlH was performed. It was found that the reduction with the system CeCl3 ? 7 H2O-NaBH4 in methanol at 20°C is the most practical procedure for the synthesis of (-)-carveol. Solvolysis of (-)-carvyl methanesulfonate gave products of SN2 and SN2' replacement of the methylsulfonyloxy group, the latter slightly prevailing. Overman rearrangement of (-)-carveol resulted in the formation of the corresponding trichloroacetamide derivative, and intramolecular iodoetherification of the title compound afforded 6-iodomethyl-2,6-dimethyl-7-oxabicyclo[3.2.1]oct-2-ene.
