Check Digit Verification of cas no
The CAS Registry Mumber 1373038-59-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,3,0,3 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1373038-59:
(9*1)+(8*3)+(7*7)+(6*3)+(5*0)+(4*3)+(3*8)+(2*5)+(1*9)=155
155 % 10 = 5
So 1373038-59-5 is a valid CAS Registry Number.
