Check Digit Verification of cas no
The CAS Registry Mumber 2091-91-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,9 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2091-91:
(6*2)+(5*0)+(4*9)+(3*1)+(2*9)+(1*1)=70
70 % 10 = 0
So 2091-91-0 is a valid CAS Registry Number.
