880256-26-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 880256-26-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,0,2,5 and 6 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 880256-26:
(8*8)+(7*8)+(6*0)+(5*2)+(4*5)+(3*6)+(2*2)+(1*6)=178
178 % 10 = 8
So 880256-26-8 is a valid CAS Registry Number.
