253670-66-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 253670-66-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,6,7 and 0 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 253670-66:
(8*2)+(7*5)+(6*3)+(5*6)+(4*7)+(3*0)+(2*6)+(1*6)=145
145 % 10 = 5
So 253670-66-5 is a valid CAS Registry Number.
