Uses

(1R,2S)-1,2-Bis(4-methoxyphenyl)ethane-1,2-diamine is a fluorogenic reagent for reducing carbohydrates

Check Digit Verification of cas no

The CAS Registry Mumber 58520-45-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,5,2 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 58520-45:
(7*5)+(6*8)+(5*5)+(4*2)+(3*0)+(2*4)+(1*5)=129
129 % 10 = 9
So 58520-45-9 is a valid CAS Registry Number.
