Check Digit Verification of cas no

The CAS Registry Mumber 99464-25-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,4,6 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 99464-25:
(7*9)+(6*9)+(5*4)+(4*6)+(3*4)+(2*2)+(1*5)=182
182 % 10 = 2
So 99464-25-2 is a valid CAS Registry Number.

Zinc homologation-elimination reaction of α-sulfinyl carbanions as a new route to olefins

Abramovitch, Adi,Marek, Ilan

experimental part, p. 4924 - 4931 (2009/05/27)

α-Lithiosulfinyl carbanions react either intermolecularly, after transmetalation into an organocopper derivative in an SN2-type process, with zinc carbenoids, or intramolecularly by higher-order zincates through a tandem zinc homologation-β-elimination reaction into the corresponding alkenes. α,α- and α,β-Disubstituted alkenes can also be produced through these two methodologies. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
