Check Digit Verification of cas no

The CAS Registry Mumber 136777-07-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,7,7 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 136777-07:
(8*1)+(7*3)+(6*6)+(5*7)+(4*7)+(3*7)+(2*0)+(1*7)=156
156 % 10 = 6
So 136777-07-6 is a valid CAS Registry Number.

Evidence for correlated rotation and diastereoisomer discrimination in (η4-diene)Fe(CO)2L complexes: the crystal and solution structures of (cyclohexadiene)Fe(CO)2P(o-tolyl)3 and (cycloheptadiene)Fe(CO)2(+)-PPh2(neomenthyl)

Howell, James A. S.,Palin, Michael G.,Tirvengadum, Marie-Claire,Cunningham, Desmond,McArdle, Patrick,et al.

, p. 269 - 286 (1991)

The solid state structure of (cyclohexadiene)Fe(CO)2P(o-tolyl)3 reveals an exo2 conformation for the phosphine.In solution, arene ring exchange in the phosphine and exchange of phosphine between equivalent basal positions of the square pyramid occur at equal rates.In solution, (cycloheptadiene)Fe(CO)2(+)-PPh2(neomenthyl) exhibits a diastereoselection between basal isomers, and crystallizes as a single diastereoisomer which has been structurally characterized.
