Check Digit Verification of cas no

The CAS Registry Mumber 146896-30-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,8,9 and 6 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 146896-30:
(8*1)+(7*4)+(6*6)+(5*8)+(4*9)+(3*6)+(2*3)+(1*0)=172
172 % 10 = 2
So 146896-30-2 is a valid CAS Registry Number.

Elimination Reactions of Terminal β-Oxy Selenoxides. Synthesis of Aryl and Vinyl Enol Ethers and of Furans, Oxazoles, and Thiazoles

Tiecco, Marcello,Testaferri, Lorenzo,Tingoli, Marco,Marini, Francesca

, p. 1349 - 1354 (1993)

Elimination reactions of terminal selenoxides holding an alkoxy group in the β-position, RCH(OR)CH2SeOPh, are usually difficult and can give rise to complex reaction mixtures.We report that these reactions take place more easily whenever the oxygen atom is linked to an unsaturated group (-CH=CHR, -Ar, -CR=O, -CH=NR).These selenoxides are easily available, and the elimination reaction was employed to effect useful syntheses of both open-chain and cyclic aryl and vinyl enol ethers.Moreover, by simple isomerization with acids or bases the cyclic derivatives can be transformed into the corresponding furans.The same procedure has been employed to synthesize substituted oxazoles and thiazoles also.
