Check Digit Verification of cas no

The CAS Registry Mumber 440659-07-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,0,6,5 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 440659-07:
(8*4)+(7*4)+(6*0)+(5*6)+(4*5)+(3*9)+(2*0)+(1*7)=144
144 % 10 = 4
So 440659-07-4 is a valid CAS Registry Number.

Nucleophilic replacement of p-(1-chloro-2,2,2-trifluoroethyl)phenols: Novel synthesis of β-trifluoromethyl-tyrosine

Gong, Yuefa,Kato, Katsuya

, p. 141 - 146 (2007/10/03)

Three para -(1-chloro-2,2,2-trifluoroethyl)phenols 2a-c were prepared by selective α-chlorination of the corresponding alcohols 1a-c. Substitution of 2a by active methylene compound 4 proceeds smoothly in the presence of an appropriate base at room temper

Facile synthesis of o- and p-(1-trifluoromethyl)-alkylated phenols via generation and reaction of quinone methides

Gong, Yuefa,Kato, Katsuya

, p. 431 - 434 (2007/10/03)

Several ortho- and para-(1-chloro-2,2,2-trifluoroethyl) phenols were prepared from the corresponding alcohols and thionyl chloride in the presence of pyridine. They reacted smoothly with sodium borohydride and Grignard reagents under mild conditions, forming 2,2,2-trifluoroethyl- or 1-trifluoromethylalkylphenols in high yields.
