226989-45-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 226989-45-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,6,9,8 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 226989-45:
(8*2)+(7*2)+(6*6)+(5*9)+(4*8)+(3*9)+(2*4)+(1*5)=183
183 % 10 = 3
So 226989-45-3 is a valid CAS Registry Number.
