1221409-61-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1221409-61-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,4,0 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1221409-61:
(9*1)+(8*2)+(7*2)+(6*1)+(5*4)+(4*0)+(3*9)+(2*6)+(1*1)=105
105 % 10 = 5
So 1221409-61-5 is a valid CAS Registry Number.
