571-70-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 571-70-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,7 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 571-70:
(5*5)+(4*7)+(3*1)+(2*7)+(1*0)=70
70 % 10 = 0
So 571-70-0 is a valid CAS Registry Number.
