Check Digit Verification of cas no
The CAS Registry Mumber 40372-66-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,3,7 and 2 respectively; the second part has 2 digits, 6 and 6 respectively.Calculate Digit Verification of CAS Registry Number 40372-66:
(7*4)+(6*0)+(5*3)+(4*7)+(3*2)+(2*6)+(1*6)=95
95 % 10 = 5
So 40372-66-5 is a valid CAS Registry Number.
