Check Digit Verification of cas no
The CAS Registry Mumber 94567-56-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,5,6 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 94567-56:
(7*9)+(6*4)+(5*5)+(4*6)+(3*7)+(2*5)+(1*6)=173
173 % 10 = 3
So 94567-56-3 is a valid CAS Registry Number.

The α-Vinylation of β-Dicarbonyl Compounds by Alk-1-enyl-lead Triacetates
Moloney, Mark G.,Pinhey, John T.
, p. 2847 - 2854 (2007/10/02)
Treatment of (E,E)-distyrylmercury (1) with lead tetra-acetate gave a mixture of (E)-styrylmercury acetate (3) and (E)-styryl-lead triacetate (2), which decomposed to (E)-styryl acetate (4) and lead(II) acetate.The vinyl-lead compound (2), generated in this way, reacted rapidly with β-keto ester (5) to give the α-(E)-styryl derivative (6) in synthetically useful yield.This procedure for the α-vinylation of (5) has been applied to the divinylmercury compounds (7)-(13), and to the synthesis of the α-(E)-styryl β-dicarbonyl compounds (28), (30), (32), and (34).Compounds (6), (28), (30), (32), and (34).Compounds (6), (28), (30), (32), and (34) have also been produced by reaction with lead compound (2) generated by reaction of tributyl-(E)-styrylstannane (36) and lead tetra-acetate.Isolation of the relatively stable cyclopent-1-enyl-lead triacetate (21b), and its reaction with keto ester (5) to give a quantitative yield of compound (18), provided evidence that vinyl-lead triacetates are the vinylating species.
