1221443-75-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1221443-75-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,4,4 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1221443-75:
(9*1)+(8*2)+(7*2)+(6*1)+(5*4)+(4*4)+(3*3)+(2*7)+(1*5)=109
109 % 10 = 9
So 1221443-75-9 is a valid CAS Registry Number.
