Check Digit Verification of cas no
The CAS Registry Mumber 70210-08-1 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 8 respectively.Calculate Digit Verification of CAS Registry Number 70210-08:
(7*7)+(6*0)+(5*2)+(4*1)+(3*0)+(2*0)+(1*8)=71
71 % 10 = 1
So 70210-08-1 is a valid CAS Registry Number.
