Check Digit Verification of cas no

The CAS Registry Mumber 107905-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,9,0 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 107905-17:
(8*1)+(7*0)+(6*7)+(5*9)+(4*0)+(3*5)+(2*1)+(1*7)=119
119 % 10 = 9
So 107905-17-9 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.
