128863-22-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128863-22-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,8,6 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 128863-22:
(8*1)+(7*2)+(6*8)+(5*8)+(4*6)+(3*3)+(2*2)+(1*2)=149
149 % 10 = 9
So 128863-22-9 is a valid CAS Registry Number.
