Check Digit Verification of cas no
The CAS Registry Mumber 6689-06-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,8 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6689-06:
(6*6)+(5*6)+(4*8)+(3*9)+(2*0)+(1*6)=131
131 % 10 = 1
So 6689-06-1 is a valid CAS Registry Number.
