Check Digit Verification of cas no

The CAS Registry Mumber 77341-88-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,3,4 and 1 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77341-88:
(7*7)+(6*7)+(5*3)+(4*4)+(3*1)+(2*8)+(1*8)=149
149 % 10 = 9
So 77341-88-9 is a valid CAS Registry Number.

Heteropolyacid-catalyzed direct deoxygenation of propargyl and allyl alcohols

Egi, Masahiro,Kawai, Takuya,Umemura, Megumi,Akai, Shuji

, p. 7092 - 7097 (2012/10/07)

The combination of H3[PW12O40] ?nH2O (1 mol %) and Et3SiH led to the direct catalytic deoxygenation of propargyl alcohols, in which proper solvent selection Cl(CH2)2Cl vs CF3CH2OH was the key to obtaining better product yields. Under similar conditions, the deoxygenation of allyl alcohols proceeded to give thermodynamically stable alkenes with migration of the double bonds in good yields.
