Check Digit Verification of cas no

The CAS Registry Mumber 220548-41-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,5,4 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 220548-41:
(8*2)+(7*2)+(6*0)+(5*5)+(4*4)+(3*8)+(2*4)+(1*1)=104
104 % 10 = 4
So 220548-41-4 is a valid CAS Registry Number.

Synthesis and structure of a heterotrinuclear complex bridged by 2,6-bis(diphenylphosphino)pyridine, [Ir2Cu(CO)2Cl2(MeCN){μ-(Ph2P)2py}2](ClO4)

Kuang, Shan-Ming,Zhang, Zheng-Zhi,Wang, Qi-Guang,Mak, Thomas C. W.

, p. 493 - 496 (2008/10/08)

The complex Ir2(CO)2Cl2{μ-Ph2P)2py}2, which was synthesized from [Ir(cod)Cl]2 and (Ph2P)2py [(Ph2P)2py=2,6-bis(diphenylphosphino)pyridine)], reacted with [Cu(MeCN4)](ClO4) to form the heterotrinuclear complex [Ir2Cu(CO)2Cl2(MeCN){μ-(Ph2P)2py}2](ClO4), whose structure has been determined by X-ray crystallography.
