Check Digit Verification of cas no
The CAS Registry Mumber 200119-87-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,1,1 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 200119-87:
(8*2)+(7*0)+(6*0)+(5*1)+(4*1)+(3*9)+(2*8)+(1*7)=75
75 % 10 = 5
So 200119-87-5 is a valid CAS Registry Number.
