130826-84-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130826-84-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,8,2 and 6 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 130826-84:
(8*1)+(7*3)+(6*0)+(5*8)+(4*2)+(3*6)+(2*8)+(1*4)=115
115 % 10 = 5
So 130826-84-5 is a valid CAS Registry Number.
