20682-69-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20682-69-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,6,8 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20682-69:
(7*2)+(6*0)+(5*6)+(4*8)+(3*2)+(2*6)+(1*9)=103
103 % 10 = 3
So 20682-69-3 is a valid CAS Registry Number.
