Check Digit Verification of cas no

The CAS Registry Mumber 521950-38-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,1,9,5 and 0 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 521950-38:
(8*5)+(7*2)+(6*1)+(5*9)+(4*5)+(3*0)+(2*3)+(1*8)=139
139 % 10 = 9
So 521950-38-9 is a valid CAS Registry Number.

Oxygen-promoted palladium(II) catalysis: Facile C(sp2)-C(sp 2) bond formation via cross-coupling of alkenylboronic compounds and olefins

Cheol, Hwan Yoon,Kyung, Soo Yoo,Sung, Wook Yi,Mishra, Rajesh K.,Kyung, Woon Jung

, p. 4037 - 4039 (2004)

(Chemical Equation Presented) Oxygen-promoted Pd(II) catalysis facilitated the synthesis of conjugated dienes by cross-coupling of alkenylboronic compounds and various olefins including highly substituted alkenes and cyclohexenone. Under mild conditions, these versatile reactions were efficient and highly stereoselective.
