220771-56-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220771-56-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,7,7 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 220771-56:
(8*2)+(7*2)+(6*0)+(5*7)+(4*7)+(3*1)+(2*5)+(1*6)=112
112 % 10 = 2
So 220771-56-2 is a valid CAS Registry Number.
