219951-25-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 219951-25-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,9,5 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 219951-25:
(8*2)+(7*1)+(6*9)+(5*9)+(4*5)+(3*1)+(2*2)+(1*5)=154
154 % 10 = 4
So 219951-25-4 is a valid CAS Registry Number.
