Check Digit Verification of cas no

The CAS Registry Mumber 302590-78-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,2,5,9 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 302590-78:
(8*3)+(7*0)+(6*2)+(5*5)+(4*9)+(3*0)+(2*7)+(1*8)=119
119 % 10 = 9
So 302590-78-9 is a valid CAS Registry Number.

Early transition metal compound and preparation method and intermediate thereof and application of early transition metal compound in polymerization of olefin

-

Paragraph 0319; 0320; 0325; 0326, (2019/11/13)

The invention relates to the field of catalysts for olefin polymerization, in particular to an early transition metal compound and a preparation method and intermediate thereof and application of theearly transition metal compound in polymerization of olefin. The early transition metal compound is a compound represented by a formula (1). When the early transition metal compound or crystal of theearly transition metal compound is applied to catalysis of olefin, high catalytic activity is achieved, and excellent catalytic activity is achieved in a wide range of polymerization conditions; and the catalyst has low cost, and is favorable for industrial production.
