Check Digit Verification of cas no
The CAS Registry Mumber 63689-66-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,6,8 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 63689-66:
(7*6)+(6*3)+(5*6)+(4*8)+(3*9)+(2*6)+(1*6)=167
167 % 10 = 7
So 63689-66-7 is a valid CAS Registry Number.
