Check Digit Verification of cas no
The CAS Registry Mumber 4916-40-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,1 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4916-40:
(6*4)+(5*9)+(4*1)+(3*6)+(2*4)+(1*0)=99
99 % 10 = 9
So 4916-40-9 is a valid CAS Registry Number.
