820223-92-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 820223-92-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,2,0,2,2 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 820223-92:
(8*8)+(7*2)+(6*0)+(5*2)+(4*2)+(3*3)+(2*9)+(1*2)=125
125 % 10 = 5
So 820223-92-5 is a valid CAS Registry Number.
