Check Digit Verification of cas no

The CAS Registry Mumber 1884-33-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,8 and 4 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1884-33:
(6*1)+(5*8)+(4*8)+(3*4)+(2*3)+(1*3)=99
99 % 10 = 9
So 1884-33-9 is a valid CAS Registry Number.

One-pot tandem hydrophenylation and ionic hydrogenation of 3-phenylpropynoic acid derivatives under superelectrophilic activation

Nilov, Denis I.,Vasilyev, Aleksander V.

, p. 5714 - 5717 (2015)

The reactions of esters and amides of 3-phenylpropynoic acid with strong Lewis acids AlX3 (X = Cl, Br) or conjugate Br?nsted-Lewis superacids HX-AlX3 (X = Cl, Br) in benzene and cyclohexane at room temperature afforded 3,3-diphenylpropanoic acid derivatives in up to 94% yield. This tandem reaction of the acetylene bond proceeded by hydrophenylation followed by ionic hydrogenation.
