Check Digit Verification of cas no

The CAS Registry Mumber 127223-15-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,2,2 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 127223-15:
(8*1)+(7*2)+(6*7)+(5*2)+(4*2)+(3*3)+(2*1)+(1*5)=98
98 % 10 = 8
So 127223-15-8 is a valid CAS Registry Number.

Reactions of Carbonyl Compounds with Benzyl Chloromethyl Ether of Diiodomethane in the Presence of Samarium(II) Iodide or Metallic Samarium. New Routes to 1,2-Diols, Iodohydrins and Cyclopropanols

Carbonyl compounds react with benzyl chloromethyl ether in the presence of samarium(II) iodide to afford the corresponding addition products which, when subsequently hydrogenolysed, yield 1,2-diols.Simple aldehydes and ketones react with diiodomethane in the presence of samarium metal to give iodohydrins in good yields.Under similar reaction conditions, α-halogeno substituted ketones and aromatic 1,4-diketones are converted into cyclopropanols.These cyclopropanations have been shown to rpoceed through the initial generation of samarium enolates, followed by the Simmons-Smith type reaction.A novel transformation of esters to cyclopropanols via tandem one-carbon homologation is also described.
