28256-63-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 28256-63-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,2,5 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 28256-63:
(7*2)+(6*8)+(5*2)+(4*5)+(3*6)+(2*6)+(1*3)=125
125 % 10 = 5
So 28256-63-5 is a valid CAS Registry Number.

Selective homologation of ketones and aldehydes with diazoalkanes promoted by organoaluminum reagents

Maruoka,Concepcion,Yamamoto

, p. 1283 - 1290 (2007/10/02)

Organoaluminum-promoted single homologation or ring expansion of ketones and aldehydes with diazoalkanes has been described, and among various organoaluminium reagents, exceptionally bulky methylaluminum bis(2,6-di-tert-butyl-4-methylphenoxide) (MAD) is found to be highly effective for the selective homologation of various ketones and aldehydes.
