113419-87-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113419-87-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,4,1 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 113419-87:
(8*1)+(7*1)+(6*3)+(5*4)+(4*1)+(3*9)+(2*8)+(1*7)=107
107 % 10 = 7
So 113419-87-7 is a valid CAS Registry Number.
