Check Digit Verification of cas no

The CAS Registry Mumber 149589-59-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,5,8 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 149589-59:
(8*1)+(7*4)+(6*9)+(5*5)+(4*8)+(3*9)+(2*5)+(1*9)=193
193 % 10 = 3
So 149589-59-3 is a valid CAS Registry Number.

Synthesis and characterization of hydroxylated polychlorinated biphenyls (PCBs) identified in human serum

Safe,Safe, Stephen,Washburn,Washburn, Kent,Zacharewski,Zacharewski, Timothy,Phillips,Phillips, Timothy

, p. 3017 - 3023 (1995)

Hydroxylated polychlorinated biphenyls (PCBs) have been identified in wildlife and human samples. Most of these compounds are highly chlorinated (penta-hepatachloro) and contain a single meta- or para-hydroxyl group. Using the Cadogan coupling procedure, the following hydroxy-PCBs congeners were synthesized: 2,3,3',4',5-pentachloro-4-biphenylol, 2,3',4,4',5-pentachloro-3-biphenylol, 2',3,3',4',5-pentachloro-4-biphenylol, 2,2',3',4,4'-pentachloro-3-biphenylol, 2,2',3,3',4',5-pentachloro-4-biphenylol, 2,2',3',4,4',5-hexachloro-3-biphenylol, 2,2',3,4',5,5'-hexachloro-4-biphenylol, 2,2',3,3',4',5,5'-heptachloro-4-biphenyl 2,2',3',4,4',5,5'-heptachloro-3-biphenylol, 2,2',3,4',5,5',6-heptachloro-4-biphenylol. Many of these compounds have been detected as residues in human serum and current studies are investigating their activities as agonists and antagonists for several endocrine-mediated responses.
