205682-80-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 205682-80-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,6,8 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 205682-80:
(8*2)+(7*0)+(6*5)+(5*6)+(4*8)+(3*2)+(2*8)+(1*0)=130
130 % 10 = 0
So 205682-80-0 is a valid CAS Registry Number.
