Check Digit Verification of cas no
The CAS Registry Mumber 1966-16-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,6 and 6 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1966-16:
(6*1)+(5*9)+(4*6)+(3*6)+(2*1)+(1*6)=101
101 % 10 = 1
So 1966-16-1 is a valid CAS Registry Number.
