Check Digit Verification of cas no

The CAS Registry Mumber 76335-36-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,3,3 and 5 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 76335-36:
(7*7)+(6*6)+(5*3)+(4*3)+(3*5)+(2*3)+(1*6)=139
139 % 10 = 9
So 76335-36-9 is a valid CAS Registry Number.

Diastereoselective three-component Mannich reaction catalyzed by silica-supported ferric hydrogensulfate

Eshghi, Hossein,Rahimizadeh, Mohammad,Hosseini, Mohsen,Javadian-Saraf, Aida

, p. 197 - 203 (2013/07/27)

A highly anti-diastereoselective three-component Mannich reaction of aromatic amines and aromatic aldehydes with cyclohexanone in the presence of silica-supported ferric hydrogensulfate has been developed. The best selectivity was obtained where there were electron-donating groups on both aldehyde and amine. Selectivity decreases when electron-withdrawing groups are present on the aldehyde; in these cases selectivity is improved if an electron-donating group is present on the amine.
