Check Digit Verification of cas no
The CAS Registry Mumber 21199-25-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,9 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 21199-25:
(7*2)+(6*1)+(5*1)+(4*9)+(3*9)+(2*2)+(1*5)=97
97 % 10 = 7
So 21199-25-7 is a valid CAS Registry Number.
