Check Digit Verification of cas no
The CAS Registry Mumber 40520-16-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,5,2 and 0 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 40520-16:
(7*4)+(6*0)+(5*5)+(4*2)+(3*0)+(2*1)+(1*6)=69
69 % 10 = 9
