Check Digit Verification of cas no

The CAS Registry Mumber 69940-86-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,9,4 and 0 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 69940-86:
(7*6)+(6*9)+(5*9)+(4*4)+(3*0)+(2*8)+(1*6)=179
179 % 10 = 9
So 69940-86-9 is a valid CAS Registry Number.

Asymmetric hydrogenation of β - methylcinnamates of phenylalkylmethanols. Catalyst-phenyl groups interactions in the preferred adsorption conformation

Gallina, Carlo,Lucente, Gino,Pinnen, Francesco

, p. 2361 - 2363 (1978)

The β-methylcinnamates of four S-alkylphenylmethanols have been hydrogenated on Pt catalyst. The observed asymmetric inductions suggest that simultaneous bonded interactions of both the phenyl groups with the catalyst in the transition states do not occur.
