Check Digit Verification of cas no

The CAS Registry Mumber 161772-58-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,7,7 and 2 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 161772-58:
(8*1)+(7*6)+(6*1)+(5*7)+(4*7)+(3*2)+(2*5)+(1*8)=143
143 % 10 = 3
So 161772-58-3 is a valid CAS Registry Number.

Synthesis, photophysical, photochemical and electrochemical properties of rhenium(I) diimine complexes with photoisomerizable pyridyl-azo, -ethenyl or -ethyl ligands

Yam, Vivian Wing-Wah,Lau, Victor Chor-Yue,Wu, Li-Xin

, p. 1461 - 1468 (1998)

A series of rhenium(I) diimine complexes with pyridyl-azo, -ethenyl or -ethyl type ligands, [Re(CO)3(N-N)L]ClO4 and [{Re(CO)3(N-N)}2L′][ClO4]2 {N-N = 2,2′-bipyridine (bpy), 1,10-phenanthroline (phen); L = 4-phenylazopyridine (PHAZO), 4-styrylpyridine (STYPY), [2-(4-pyridyl)ethyl]benzene (PEB), 4-(4-nitrostyryl)pyridine (NSP); L′ = 4,4′-azopyridine (AZO), 1,4-bis[2-(4-pyridyl)ethenyl]benzene (BPENB), 1,4-bis[2-(4-pyridyl)ethyl]benzene (BPEB)} have been synthesized and their photophysical properties studied. The quantum yields for the photoinduced isomerization of the complexes [Re(CO)3(bpy)(NSP)]+ and [Re(CO)3(phen)(NSP)]+ have been determined.
