Check Digit Verification of cas no

The CAS Registry Mumber 154267-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,2,6 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 154267-31:
(8*1)+(7*5)+(6*4)+(5*2)+(4*6)+(3*7)+(2*3)+(1*1)=129
129 % 10 = 9
So 154267-31-9 is a valid CAS Registry Number.

Chemical Behaviour of Trimethylammonium N-Methylides Substituted with Nitrogen-containing Heteroaromatic Rings. Rearrangement of N,N-Dimethyl(pyridylmethyl)ammonium, N,N-Dimethyl-(1-methylpyrrolylmethyl)ammonium and N,N-Dimethyl-(1-methylindolylmethyl)ammonium N-Methylides

, p. 393 - 398 (2007/10/02)

N,N-Dimethyl(pyridylmethyl)ammonium N-methylides 2, 6 11, N,N-dimethyl(1-methylpyrrolylmethyl)ammonium N-methylides 15, 20, and N,N-dimethyl(1-methylindolylmethyl)ammonium N-methylides 23, 28 were generated by fluoride ion-induced desilylation of the corresponding (trimethylsilyl)methylammonium salts 1, 5, 10, 14, 19, 22 and 27, and the isomerisation products of the ylides were investigated.
