Check Digit Verification of cas no

The CAS Registry Mumber 590422-98-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,9,0,4,2 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 590422-98:
(8*5)+(7*9)+(6*0)+(5*4)+(4*2)+(3*2)+(2*9)+(1*8)=163
163 % 10 = 3
So 590422-98-3 is a valid CAS Registry Number.

Highly regiocontrolled pd-catalyzed cross-coupling reaction of terminal alkynes and allenylphosphine oxides

Rubin, Michael,Markov, Jelena,Chuprakov, Stepan,Wink, Donald J.,Gevorgyan, Vladimir

, p. 6251 - 6256 (2007/10/03)

The cross-coupling of a variety of terminal alkynes 1 with allenylphosphine oxides 2 catalyzed by a Pd(OAc)2-TDMPP system provided conjugated endo-enynes 3 solely, while the TCPC-catalyzed reaction of the same regents led to the exclusive forma
