280551-18-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 280551-18-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,0,5,5 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 280551-18:
(8*2)+(7*8)+(6*0)+(5*5)+(4*5)+(3*1)+(2*1)+(1*8)=130
130 % 10 = 0
So 280551-18-0 is a valid CAS Registry Number.
