Chemical Properties
white, monoclinic crystal(s) or crystal(s) powder(s); oxidizes gradually to sulfate in air; used as a photographic developer, as a food and wine preservative [HAW93] [MER06] [KIR82]Check Digit Verification of cas no
The CAS Registry Mumber 7790-56-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,9 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.Calculate Digit Verification of CAS Registry Number 7790-56:
(6*7)+(5*7)+(4*9)+(3*0)+(2*5)+(1*6)=129
129 % 10 = 9
So 7790-56-9 is a valid CAS Registry Number.
