Check Digit Verification of cas no
The CAS Registry Mumber 20576-70-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,7 and 6 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20576-70:
(7*2)+(6*0)+(5*5)+(4*7)+(3*6)+(2*7)+(1*0)=99
99 % 10 = 9
So 20576-70-9 is a valid CAS Registry Number.
