Check Digit Verification of cas no

The CAS Registry Mumber 134023-76-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,0,2 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 134023-76:
(8*1)+(7*3)+(6*4)+(5*0)+(4*2)+(3*3)+(2*7)+(1*6)=90
90 % 10 = 0
So 134023-76-0 is a valid CAS Registry Number.

Electroorganic Chemistry. 144. Electroreductive Coupling of Ketones with O-Methyl Oximes, N,N-Dimethylhydrazones, amd Nitrones. A Convenient Route to Synthesis of β-Amino Alcohol

Shono, Tatsuya,Kise, Naoki,Fujimoto, Taku,Yamanami, Ayuko,Nomura, Ryoji

, p. 1730 - 1740 (2007/10/02)

The intermolecular coupling of a variety of ketones with some types of O-methyl oximes took place when a mixture of both components was electrochemically reduced in i-PrOH with an Sn cathode.The product, β-methoxyamino alcohol was easily converted to β-amino alcohol by simple reduction.A chiral ligand effective for the enantioselective addition of diethylzinc to an aldehyde was easily obtained from the product formed by the electroreductive coupling of (-)-menthone with O-methylacetaldoxime.The intermolecular coupling of a ketone with a N,N-dimethylhydrazone or nitrone was also promoted by the electroreduction.Furthermore, the electroreductive coupling of a carbonyl group with an intramolecular O-methyl oxime moiety gave the corresponding cyclized product stereoselectively.
