Check Digit Verification of cas no

The CAS Registry Mumber 13344-08-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,3,4 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13344-08:
(7*1)+(6*3)+(5*3)+(4*4)+(3*4)+(2*0)+(1*8)=76
76 % 10 = 6
So 13344-08-6 is a valid CAS Registry Number.

Kinetics and mechanism of the anilinolyses of aryl dimethyl, methyl phenyl and diphenyl phosphinates

Dey, Nilay Kumar,Kim, Chan Kyung,Lee, Hai Whang

supporting information; experimental part, p. 717 - 724 (2011/04/16)

The reactions of Z-aryl dimethyl (1), methyl phenyl (2), and diphenyl (3) phosphinates with X-anilines in dimethyl sulfoxide at 60.0 °C are studied kinetically. Kinetic results yield the primary normal deuterium kinetic isotope effects (DKIEs) involving deuterated aniline (XC6H4ND 2) nucleophiles, kH/kD = 1.03-1.17, 1.15-1.29, and 1.24-1.51, and the cross-interaction constants (CICs), ρXZ = 0.37, 0.34, and 0.65 for 1, 2, and 3, respectively. The steric effects of the ligands (R1 and R2) on reaction rates play a role, but are relatively much smaller compared to other phosphinate systems. A stepwise mechanism with a rate-limiting leaving group expulsion from the intermediate is proposed on the basis of the CICs positive signs. The dominant frontside nucleophilic attack through a hydrogen-bonded, four-center-type transition state is proposed on the basis of primary normal DKIEs and large magnitudes of the CICs for 2 and 3, while both frontside and backside attack are proposed on the basis of relatively small primary normal DKIEs for 1.
