73454-70-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73454-70-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,4,5 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 73454-70:
(7*7)+(6*3)+(5*4)+(4*5)+(3*4)+(2*7)+(1*0)=133
133 % 10 = 3
So 73454-70-3 is a valid CAS Registry Number.
