Check Digit Verification of cas no
The CAS Registry Mumber 42373-04-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,3,7 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 42373-04:
(7*4)+(6*2)+(5*3)+(4*7)+(3*3)+(2*0)+(1*4)=96
96 % 10 = 6
So 42373-04-6 is a valid CAS Registry Number.
