Check Digit Verification of cas no
The CAS Registry Mumber 6486-29-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,8 and 6 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6486-29:
(6*6)+(5*4)+(4*8)+(3*6)+(2*2)+(1*9)=119
119 % 10 = 9
So 6486-29-9 is a valid CAS Registry Number.
