Check Digit Verification of cas no

The CAS Registry Mumber 1020254-99-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,0,2,5 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1020254-99:
(9*1)+(8*0)+(7*2)+(6*0)+(5*2)+(4*5)+(3*4)+(2*9)+(1*9)=92
92 % 10 = 2
So 1020254-99-2 is a valid CAS Registry Number.

Synthesis of arylallenes by palladium-catalyzed retro-propargylation of homopropargyl alcohols

Hayashi, Sayuri,Hirano, Koji,Yorimitsu, Hideki,Oshima, Koichiro

, p. 5048 - 5049 (2008/10/09)

Treatment of tertiary homopropargyl alcohol with aryl halide under palladium catalysis provided arylallenes regioselectively. The reaction includes retro-propargylation, which proceeds in a concerted fashion via a cyclic transition state and transfers the stereochemistry of homopropargyl alcohols through C-C bond cleavage. The present method enables the use of homopropargyl alcohols as allenylmetal equivalents. Copyright
