1248826-58-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1248826-58-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,8,8,2 and 6 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1248826-58:
(9*1)+(8*2)+(7*4)+(6*8)+(5*8)+(4*2)+(3*6)+(2*5)+(1*8)=185
185 % 10 = 5
So 1248826-58-5 is a valid CAS Registry Number.
