115663-31-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 115663-31-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,6,6 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 115663-31:
(8*1)+(7*1)+(6*5)+(5*6)+(4*6)+(3*3)+(2*3)+(1*1)=115
115 % 10 = 5
So 115663-31-5 is a valid CAS Registry Number.
