Check Digit Verification of cas no
The CAS Registry Mumber 66690-78-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,6,9 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 66690-78:
(7*6)+(6*6)+(5*6)+(4*9)+(3*0)+(2*7)+(1*8)=166
166 % 10 = 6
So 66690-78-6 is a valid CAS Registry Number.
