Check Digit Verification of cas no
The CAS Registry Mumber 89671-18-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,6,7 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 89671-18:
(7*8)+(6*9)+(5*6)+(4*7)+(3*1)+(2*1)+(1*8)=181
181 % 10 = 1
So 89671-18-1 is a valid CAS Registry Number.
