66437-20-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 66437-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,4,3 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 66437-20:
(7*6)+(6*6)+(5*4)+(4*3)+(3*7)+(2*2)+(1*0)=135
135 % 10 = 5
So 66437-20-5 is a valid CAS Registry Number.
