Check Digit Verification of cas no
The CAS Registry Mumber 17858-15-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,8,5 and 8 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 17858-15:
(7*1)+(6*7)+(5*8)+(4*5)+(3*8)+(2*1)+(1*5)=140
140 % 10 = 0
So 17858-15-0 is a valid CAS Registry Number.
