Check Digit Verification of cas no

The CAS Registry Mumber 1417538-03-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,7,5,3 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1417538-03:
(9*1)+(8*4)+(7*1)+(6*7)+(5*5)+(4*3)+(3*8)+(2*0)+(1*3)=154
154 % 10 = 4
So 1417538-03-4 is a valid CAS Registry Number.

A new mild method for the C-acylation of ketone enolates. a convenient synthesis of β-keto-esters,-thionoesters, and-thioesters

Hale, Karl J.,Grabski, Milosz,Flasz, Jakub T.

, p. 370 - 373 (2013)

A new method for ketone enolate C-acylation is described which utilizes alkyl pentafluorophenylcarbonates, thiocarbonates, and thionocarbonates as the reactive acylating agents, and MgBr2·Et2O, DMAP, and i-Pr2NEt as the reagents for enolization. A wide range of ketones have been observed to undergo clean C-acylation via this protocol.
