Check Digit Verification of cas no
The CAS Registry Mumber 8027-29-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,2 and 7 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 8027-29:
(6*8)+(5*0)+(4*2)+(3*7)+(2*2)+(1*9)=90
90 % 10 = 0
So 8027-29-0 is a valid CAS Registry Number.
