Check Digit Verification of cas no
The CAS Registry Mumber 18678-58-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,6,7 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 18678-58:
(7*1)+(6*8)+(5*6)+(4*7)+(3*8)+(2*5)+(1*8)=155
155 % 10 = 5
So 18678-58-5 is a valid CAS Registry Number.
