539823-59-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 539823-59-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,3,9,8,2 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 539823-59:
(8*5)+(7*3)+(6*9)+(5*8)+(4*2)+(3*3)+(2*5)+(1*9)=191
191 % 10 = 1
So 539823-59-1 is a valid CAS Registry Number.
