9074-11-7 Usage
Purification Methods
Dihydropteridine reductase is purified to homogeneity on a naphthoquinone affinity adsorbent, followed by DEAE-Sephadex and CM-Sephadex chromatography. [Firgaira, Cotton and Danks, Biochem J 197 31 1981.] [For other dihydropteridine reductases see Armarego et al. Med Res Rev 4(3) 267 1984.] 3,4-Dihydroxyphenylalanine-containing proteins. Boronate affinity chromatography is used in the selective binding of proteins containing 3,4-dihydroxyphenylalanine to a m-phenylboronate agarose column and eluted with 1M NH4OAc at pH 10. [Hankus et al. Anal Biochem 150 187 1986.]
Check Digit Verification of cas no
The CAS Registry Mumber 9074-11-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,7 and 4 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 9074-11:
(6*9)+(5*0)+(4*7)+(3*4)+(2*1)+(1*1)=97
97 % 10 = 7
So 9074-11-7 is a valid CAS Registry Number.
