221248-11-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 221248-11-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,2,4 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 221248-11:
(8*2)+(7*2)+(6*1)+(5*2)+(4*4)+(3*8)+(2*1)+(1*1)=89
89 % 10 = 9
So 221248-11-9 is a valid CAS Registry Number.
