Check Digit Verification of cas no
The CAS Registry Mumber 70210-00-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,2,1 and 0 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 70210-00:
(7*7)+(6*0)+(5*2)+(4*1)+(3*0)+(2*0)+(1*0)=63
63 % 10 = 3
So 70210-00-3 is a valid CAS Registry Number.
