521315-91-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 521315-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,1,3,1 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 521315-91:
(8*5)+(7*2)+(6*1)+(5*3)+(4*1)+(3*5)+(2*9)+(1*1)=113
113 % 10 = 3
So 521315-91-3 is a valid CAS Registry Number.
