Check Digit Verification of cas no

The CAS Registry Mumber 110397-48-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,3,9 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 110397-48:
(8*1)+(7*1)+(6*0)+(5*3)+(4*9)+(3*7)+(2*4)+(1*8)=103
103 % 10 = 3
So 110397-48-3 is a valid CAS Registry Number.

New synthetic technology for the synthesis of hindered α-diazoketones via acyl mesylates

Nicolaou,Baran, Phil S.,Zhong, Yong-Li,Choi, Ha-Soon,Fong, Kin Chiu,He, Yun,Yoon, Won Hyung

, p. 883 - 886 (2008/02/09)

(equation presented) A mild and reliable one-pot protocol for the elaboration of sterically demanding carboxylic acids into α-diazoketones via acyl mesylates has been developed. Aside from delineating the reaction parameters which render this strategy quite general for hindered carboxylic acids, we have directly proven the existence of the fleeting acyl mesylate group as the reactive species in these reactions and shed light onto the differing mechanisms which are operative in the activation of hindered and simple carboxylic acids with methanesulfonyl chloride.
