131682-28-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131682-28-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,6,8 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 131682-28:
(8*1)+(7*3)+(6*1)+(5*6)+(4*8)+(3*2)+(2*2)+(1*8)=115
115 % 10 = 5
So 131682-28-5 is a valid CAS Registry Number.
