5977-33-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5977-33-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,7 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5977-33:
(6*5)+(5*9)+(4*7)+(3*7)+(2*3)+(1*3)=133
133 % 10 = 3
So 5977-33-3 is a valid CAS Registry Number.

Effects of tetrahydropterines on the generation of quinones catalyzed by tyrosinase

Garcia-Molina, Francis,Munoz-Munoz, Joseph Louis,Martinez-Ortiz, Francis,Tudela, Joseph,Garcia-Canovas, Francis,Rodriguez-Lopez, Joseph Neptune

scheme or table, p. 1108 - 1109 (2011/05/04)

Tetrahydrobiopterine (6BH4) can diminish the oxidative stress undergone by keratinocytes and melanocytes by reducing the o-quinones generated by the oxidation of the corresponding o-diphenols. We found that 6BH4 and their analogs reduced all the o-quinones studied. The formal potentials of different quinone/diphenol pairs indicate that the o-quinones with withdrawing groups are more potent oxidants than those with donating groups.
