Check Digit Verification of cas no

The CAS Registry Mumber 101448-09-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,4,4 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 101448-09:
(8*1)+(7*0)+(6*1)+(5*4)+(4*4)+(3*8)+(2*0)+(1*9)=83
83 % 10 = 3
So 101448-09-3 is a valid CAS Registry Number.

CHEMISTRY OF ENOL ETHERS. LXXVII. SYNTHESIS OF ACETALS OF PHENYLSUBSTITUTED GLUTACONALDEHYDES

Makin, S. M.,Kruglikova, R. I.,Lonina, N. N.

, p. 847 - 852 (2007/10/02)

The condensation of the acetals of acetophenone and acetaldehyde with enol ethers, as a result of which 2- and 3-phenyl-1,1,3-trialkoxybutanes were obtained, was studied.The acid hydrolysis of the products leads to the formation of 2- and 3-phenylbutenals, from which 2- and 3-phenyl-1-trimethylsilyloxy-1,3-butadienes were obtained by the action of trimethylchlorosilane and triethylamine.The reaction of the silyloxydienes with ethyl orthoformate in the presence of zinc chloride as catalyst gave the monoacetals of α- and β-phenylglutaconaldehydes, which were converted into the corresponding bisacetals by the further action of the orthoformate.
