539021-44-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 539021-44-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,3,9,0,2 and 1 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 539021-44:
(8*5)+(7*3)+(6*9)+(5*0)+(4*2)+(3*1)+(2*4)+(1*4)=138
138 % 10 = 8
So 539021-44-8 is a valid CAS Registry Number.
