Check Digit Verification of cas no

The CAS Registry Mumber 39999-20-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,9,9 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 39999-20:
(7*3)+(6*9)+(5*9)+(4*9)+(3*9)+(2*2)+(1*0)=187
187 % 10 = 7
So 39999-20-7 is a valid CAS Registry Number.

Solvent effects on the steric course of the solvolysis of tertiary acyclic derivatives

Mueller, Paul,Rossier, Jean-Claude

, p. 2232 - 2237 (2007/10/03)

The solvolysis of (R)-3-chloro-3,7-dimethyloctane (2), of the corresponding hydrogen phthalate (S)-4g, and of the p-nitrobenzoate (S)-4h proceeds with up to 87% inversion of configuration in solvents such as methanol or ethanol. The degree of inversion decreases in more dissociating solvents. In 2,2,2-trifluoroethanol (TFE), up to 40% retention of configuration occurs.
