216257-25-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 216257-25-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,2,5 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 216257-25:
(8*2)+(7*1)+(6*6)+(5*2)+(4*5)+(3*7)+(2*2)+(1*5)=119
119 % 10 = 9
So 216257-25-9 is a valid CAS Registry Number.
