Check Digit Verification of cas no
The CAS Registry Mumber 5938-85-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,3 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5938-85:
(6*5)+(5*9)+(4*3)+(3*8)+(2*8)+(1*5)=132
132 % 10 = 2
So 5938-85-2 is a valid CAS Registry Number.
