Check Digit Verification of cas no
The CAS Registry Mumber 6860-97-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,6 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6860-97:
(6*6)+(5*8)+(4*6)+(3*0)+(2*9)+(1*7)=125
125 % 10 = 5
So 6860-97-5 is a valid CAS Registry Number.
