1220707-45-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1220707-45-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,7,0 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1220707-45:
(9*1)+(8*2)+(7*2)+(6*0)+(5*7)+(4*0)+(3*7)+(2*4)+(1*5)=108
108 % 10 = 8
So 1220707-45-8 is a valid CAS Registry Number.
