Check Digit Verification of cas no

The CAS Registry Mumber 124211-38-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,2,1 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 124211-38:
(8*1)+(7*2)+(6*4)+(5*2)+(4*1)+(3*1)+(2*3)+(1*8)=77
77 % 10 = 7
So 124211-38-7 is a valid CAS Registry Number.

Synthesis of 2-(2-Acetoxyisopropyl)-5,8-dimethyl-1,4-dihydronaphthalene (Acetyldehydrorishitinol), a Sesquiterpenic Stress Metabolite from Potatoes

Sudalai, A.,Rao, Krishna G. S.

, p. 113 - 115 (2007/10/02)

The two-step synthesis of acetyldehydrorishitinol (2), a sesquiterpenic stress metabolite produced by fungus-infested tubers of white potato (Solanum tuberosum Linn.) is described.Metal-ammonia reduction of 2-acetyl-4,8-dimethylnaphthalene (6) gives the corresponding 1,4-dihydro derivative (10) which on reaction with methylmagnesium iodide, followed by quenching with Ac2O-NaOAc affords 2.Quenching of a Grignard reaction complex of the type R1R2R3COMgX, with Ac2O-NaOAc, provides the tertiary acetates in situ in a one-pot procedure.
