Check Digit Verification of cas no
The CAS Registry Mumber 601-70-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,0 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 601-70:
(5*6)+(4*0)+(3*1)+(2*7)+(1*0)=47
47 % 10 = 7
So 601-70-7 is a valid CAS Registry Number.
