Check Digit Verification of cas no
The CAS Registry Mumber 857827-24-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,8,2 and 7 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 857827-24:
(8*8)+(7*5)+(6*7)+(5*8)+(4*2)+(3*7)+(2*2)+(1*4)=218
218 % 10 = 8
So 857827-24-8 is a valid CAS Registry Number.

KF-alumina-mediated Bargellini reaction
Rohman, Md. Rumum,Myrboh, Bekington
experimental part, p. 4772 - 4775 (2010/09/20)
KF-alumina was found to be an efficient base for the synthesis of sterically hindered α-substituted carboxylic acids. A series of Bargellini reactions were performed by using various substituted anilines, phenols, and thiophenols as nucleophiles with keto
