Check Digit Verification of cas no

The CAS Registry Mumber 801294-25-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,1,2,9 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 801294-25:
(8*8)+(7*0)+(6*1)+(5*2)+(4*9)+(3*4)+(2*2)+(1*5)=137
137 % 10 = 7
So 801294-25-7 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.
