Check Digit Verification of cas no
The CAS Registry Mumber 289915-87-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,9,1 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 289915-87:
(8*2)+(7*8)+(6*9)+(5*9)+(4*1)+(3*5)+(2*8)+(1*7)=213
213 % 10 = 3
So 289915-87-3 is a valid CAS Registry Number.
