Check Digit Verification of cas no
The CAS Registry Mumber 93951-73-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,9,5 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 93951-73:
(7*9)+(6*3)+(5*9)+(4*5)+(3*1)+(2*7)+(1*3)=166
166 % 10 = 6
So 93951-73-6 is a valid CAS Registry Number.
