6640-70-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6640-70-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,4 and 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6640-70:
(6*6)+(5*6)+(4*4)+(3*0)+(2*7)+(1*0)=96
96 % 10 = 6
So 6640-70-6 is a valid CAS Registry Number.
