Check Digit Verification of cas no

The CAS Registry Mumber 1245817-34-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,5,8,1 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1245817-34:
(9*1)+(8*2)+(7*4)+(6*5)+(5*8)+(4*1)+(3*7)+(2*3)+(1*4)=158
158 % 10 = 8
So 1245817-34-8 is a valid CAS Registry Number.

Palladium-catalyzed fluorocarbonylation using N-formylsaccharin as CO source: General access to carboxylic acid derivatives

Ueda, Tsuyoshi,Konishi, Hideyuki,Manabe, Kei

, p. 5370 - 5373 (2013/11/06)

N-Formylsaccharin, an easily accessible crystalline compound, has been employed as an efficient CO source in Pd-catalyzed fluorocarbonylation of aryl halides to afford the corresponding acyl fluorides in high yields. The reactions use a near-stoichiometric amount of the CO source (1.2 equiv) and tolerate diverse functional groups. The acyl fluorides obtained could be readily transformed into various carboxylic acid derivatives such as carboxylic acid, esters, thioesters, and amides in a one-pot procedure.
