Check Digit Verification of cas no
The CAS Registry Mumber 16766-90-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,7,6 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 16766-90:
(7*1)+(6*6)+(5*7)+(4*6)+(3*6)+(2*9)+(1*0)=138
138 % 10 = 8
So 16766-90-8 is a valid CAS Registry Number.
