Check Digit Verification of cas no
The CAS Registry Mumber 20680-48-2 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 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20680-48:
(7*2)+(6*0)+(5*6)+(4*8)+(3*0)+(2*4)+(1*8)=92
92 % 10 = 2
So 20680-48-2 is a valid CAS Registry Number.
