Check Digit Verification of cas no
The CAS Registry Mumber 40343-30-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,3,4 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 40343-30:
(7*4)+(6*0)+(5*3)+(4*4)+(3*3)+(2*3)+(1*0)=74
74 % 10 = 4
So 40343-30-4 is a valid CAS Registry Number.
