Check Digit Verification of cas no
The CAS Registry Mumber 57381-63-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,3,8 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 57381-63:
(7*5)+(6*7)+(5*3)+(4*8)+(3*1)+(2*6)+(1*3)=142
142 % 10 = 2
So 57381-63-2 is a valid CAS Registry Number.
