Check Digit Verification of cas no
The CAS Registry Mumber 89861-18-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,8,6 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 89861-18:
(7*8)+(6*9)+(5*8)+(4*6)+(3*1)+(2*1)+(1*8)=187
187 % 10 = 7
So 89861-18-7 is a valid CAS Registry Number.
