86453-74-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86453-74-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,4,5 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 86453-74:
(7*8)+(6*6)+(5*4)+(4*5)+(3*3)+(2*7)+(1*4)=159
159 % 10 = 9
So 86453-74-9 is a valid CAS Registry Number.
