53219-99-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 53219-99-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,2,1 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 53219-99:
(7*5)+(6*3)+(5*2)+(4*1)+(3*9)+(2*9)+(1*9)=121
121 % 10 = 1
So 53219-99-1 is a valid CAS Registry Number.
