92820-73-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 92820-73-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,8,2 and 0 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 92820-73:
(7*9)+(6*2)+(5*8)+(4*2)+(3*0)+(2*7)+(1*3)=140
140 % 10 = 0
So 92820-73-0 is a valid CAS Registry Number.
