Check Digit Verification of cas no
The CAS Registry Mumber 5376-03-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,7 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.Calculate Digit Verification of CAS Registry Number 5376-03:
(6*5)+(5*3)+(4*7)+(3*6)+(2*0)+(1*3)=94
94 % 10 = 4
So 5376-03-4 is a valid CAS Registry Number.
