66364-70-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 66364-70-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,3,6 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 66364-70:
(7*6)+(6*6)+(5*3)+(4*6)+(3*4)+(2*7)+(1*0)=143
143 % 10 = 3
So 66364-70-3 is a valid CAS Registry Number.
