Check Digit Verification of cas no
The CAS Registry Mumber 6809-91-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,0 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6809-91:
(6*6)+(5*8)+(4*0)+(3*9)+(2*9)+(1*1)=122
122 % 10 = 2
So 6809-91-2 is a valid CAS Registry Number.
