20682-98-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20682-98-8 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, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20682-98:
(7*2)+(6*0)+(5*6)+(4*8)+(3*2)+(2*9)+(1*8)=108
108 % 10 = 8
So 20682-98-8 is a valid CAS Registry Number.
