Check Digit Verification of cas no

The CAS Registry Mumber 1023972-54-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,3,9,7 and 2 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1023972-54:
(9*1)+(8*0)+(7*2)+(6*3)+(5*9)+(4*7)+(3*2)+(2*5)+(1*4)=134
134 % 10 = 4
So 1023972-54-4 is a valid CAS Registry Number.

Mo-Au combo catalysis for rapid 1,3-rearrangement of propargyl alcohols into α,ss-unsaturated carbonyl compounds

Egi, Masahiro,Yamaguchi, Yoshiko,Fujiwara, Noboru,Akai, Shuji

supporting information; experimental part, p. 1867 - 1870 (2009/04/18)

The combination of Mo and cationic Au catalysts dramatically accelerated the rearrangement of diverse propargyl alcohols, which includes a short reaction time, mild conditions, and high product yields. A practical application to the highly challenging primary propargyl alcohols and the N-alkynyl amides is achieved.
