Check Digit Verification of cas no

The CAS Registry Mumber 152485-84-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,4,8 and 5 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 152485-84:
(8*1)+(7*5)+(6*2)+(5*4)+(4*8)+(3*5)+(2*8)+(1*4)=142
142 % 10 = 2
So 152485-84-2 is a valid CAS Registry Number.

Constrasteric Regioselectivity of Palladium(0) Catalyzed Couplings of Alkynes with Bis(enoltriflate). Novel Syntheses of E-Configurated Dienediynes

Suffert, Jean,Eggers, Anke,Scheuplein, Stefan W.,Brueckner, Reinhard

, p. 4177 - 4180 (2007/10/02)

Two consecutive PdCl2(PPh3)2 catalyzed couplings of the bis(enoltriflate) E-2 with two different alkynes were performed as one-pot reactions; they provided 3:1-7:1 mixtures of enediynes E-3a'-l' and E-3a-l in 48-91 percent yield.Selective syntheses of suc
