Check Digit Verification of cas no

The CAS Registry Mumber 68983-12-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,9,8 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 68983-12:
(7*6)+(6*8)+(5*9)+(4*8)+(3*3)+(2*1)+(1*2)=180
180 % 10 = 0
So 68983-12-0 is a valid CAS Registry Number.

β-SUBSTITUTED ALKYLTIN HALIDES. III. SYNTHESIS OF TRIALKYLTIN HALIDES AND TETRAALKYLTINS

Burley, Joseph W.,Hutton, Ronald E.,Jolley, Michael R.J.,Groenenboom, Cornelis J.

, p. 189 - 202 (1983)

(β-Carboalkoxyethyl)tin trihalides and bis(β-carboalkoxyethyl)tin dihalides react with metallic zinc to give mixtures of the corresponding tris(β-carboalkoxyethyl)tin halides and the tetra(β-carboalkoxyethyl)tins.Bis(β-carboalkoxyethyl)tin diacetates react with metallic zinc to give only the corresponding tetra(β-carboalkoxyethyl)tin compounds.The mechanisms of these reactions are discussed.Conversion of the bis(β-carboalkoxyethyl)tin dihalides into the tris(β-carboalkoxyethyl)tin halides is believed to occur by a two-step process, with the tetra(β-carboalkoxyethyl)tin compounds as intermediate products.The 270 MHz NMR spectra of the (β-carbobutoxyethyl)tin compounds are presented.
