Check Digit Verification of cas no
The CAS Registry Mumber 40601-76-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,6,0 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 40601-76:
(7*4)+(6*0)+(5*6)+(4*0)+(3*1)+(2*7)+(1*6)=81
81 % 10 = 1
So 40601-76-1 is a valid CAS Registry Number.
