Check Digit Verification of cas no

The CAS Registry Mumber 1374021-21-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,0,2 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1374021-21:
(9*1)+(8*3)+(7*7)+(6*4)+(5*0)+(4*2)+(3*1)+(2*2)+(1*1)=122
122 % 10 = 2
So 1374021-21-2 is a valid CAS Registry Number.

Catalytic asymmetric synthesis of dihydroquinazolinones from imines and 2-aminobenzamides

Cheng, Dao-Juan,Tian, Yu,Tian, Shi-Kai

, p. 995 - 999 (2012/06/01)

An unprecedented catalytic asymmetric synthesis of aminal-containing heterocyclic compounds has been developed from imines and tethered nitrogen/nitrogen nucleophiles. In the presence of 10mol% of a commercially available chiral phosphoric acid, a range of aromatic, α,β- unsaturated, and aliphatic imines react with 2-aminobenzamides to give dihydroquinazolinones in good to excellent yields and ee. The enantioselectivity is significantly affected by the imine N-substituent through non-bonding interactions with the chiral phosphoric acid and the 2-aminobenzamide. Copyright
