Check Digit Verification of cas no

The CAS Registry Mumber 76486-89-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,4,8 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 76486-89:
(7*7)+(6*6)+(5*4)+(4*8)+(3*6)+(2*8)+(1*9)=180
180 % 10 = 0
So 76486-89-0 is a valid CAS Registry Number.

Push-Pull Substituted Allenes, VI. Synthesis and Properties of 1,1-Diethoxy-3-acylallenes

Saalfrank, Rolf W.,Paul, Winfried,Schierling, Peter

, p. 3477 - 3487 (2007/10/02)

Reaction of the non enolizing 1,2-diketones 1 with (2,2-diethoxyvinylidene)triphenylphosphorane (2) yields the 1,1-diethoxy-3-acylallenes 4 via the remarkably stable oxaphosphetanes 3.With two exceptions these allenes dimerize spontaneously to form the po
