Check Digit Verification of cas no

The CAS Registry Mumber 203383-29-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,3,8 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 203383-29:
(8*2)+(7*0)+(6*3)+(5*3)+(4*8)+(3*3)+(2*2)+(1*9)=103
103 % 10 = 3
So 203383-29-3 is a valid CAS Registry Number.

Preparations of Furans from α-Bromo Ketones and Enol Ethers Catalyzed by a Rhenium(I) Nitrogen Complex

Koga, Yuji,Kusama, Hiroyuki,Narasaka, Koichi

, p. 475 - 482 (1998)

By the catalytic use of a rhenium(I) nitrogen complex, [ReCl(N2)(PMe2Ph)4], α-keto radicals are generated from α-bromo ketones and react with vinyl ethers and silyl enol ethers intermolecularly. Various substituted furans, including tetrasubstituted furans such as furoguaiacin, are prepared by this method.
