Check Digit Verification of cas no
The CAS Registry Mumber 879894-25-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,9,8,9 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 879894-25:
(8*8)+(7*7)+(6*9)+(5*8)+(4*9)+(3*4)+(2*2)+(1*5)=264
264 % 10 = 4
So 879894-25-4 is a valid CAS Registry Number.
