3840-02-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3840-02-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,4 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3840-02:
(6*3)+(5*8)+(4*4)+(3*0)+(2*0)+(1*2)=76
76 % 10 = 6
So 3840-02-6 is a valid CAS Registry Number.

DMF Dimethyl Acetal as Carbon Source for α-Methylation of Ketones: A Hydrogenation-Hydrogenolysis Strategy of Enaminones

Borah, Ashwini,Goswami, Limi,Neog, Kashmiri,Gogoi, Pranjal

, p. 4722 - 4728 (2015/05/13)

A novel heterogeneous catalytic hydrogenation-hydrogenolysis strategy has been developed for the α-methylation of ketones via enaminones using DMF dimethyl acetal as carbon source. This strategy provides a very convenient route to α-methylated ketones using a variety of ketones without any base or oxidant. (Chemical Equation Presented).
