Check Digit Verification of cas no

The CAS Registry Mumber 124052-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,0,5 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 124052-31:
(8*1)+(7*2)+(6*4)+(5*0)+(4*5)+(3*2)+(2*3)+(1*1)=79
79 % 10 = 9
So 124052-31-9 is a valid CAS Registry Number.

FORMATION OF SPIRO ADDUCT FROM N-METHYL-N-(2,4,6-TRINITROPHENYL)GLYCINE ANION

Machacek, Vladimir,Cegan, Alexandr,Sedlak, Milos,Sterba, Vojeslav

, p. 440 - 445 (2007/10/02)

The intramolecular nucleophilic addition of N-methyl-N-(2,4,6-trinitrophenyl)glycine anion in methanol-dimethyl sulfoxide mixtures produces spiro.The spiro adduct has been identified by means of 1H and 13C NMR spectroscopy.This is the first case when the formation of a Meisenheimer adduct with carboxylate ion is observed.Logarithm of the equilibrium constant of adduct formation increases linearly with the mole fraction of dimethyl sulfoxide in its mixture with methanol.
