1573-65-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1573-65-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,7 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.Calculate Digit Verification of CAS Registry Number 1573-65:
(6*1)+(5*5)+(4*7)+(3*3)+(2*6)+(1*5)=85
85 % 10 = 5
So 1573-65-5 is a valid CAS Registry Number.
