Check Digit Verification of cas no
The CAS Registry Mumber 121590-87-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,5,9 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 121590-87:
(8*1)+(7*2)+(6*1)+(5*5)+(4*9)+(3*0)+(2*8)+(1*7)=112
112 % 10 = 2
So 121590-87-2 is a valid CAS Registry Number.
