Check Digit Verification of cas no
The CAS Registry Mumber 190717-38-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,7,1 and 7 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 190717-38:
(8*1)+(7*9)+(6*0)+(5*7)+(4*1)+(3*7)+(2*3)+(1*8)=145
145 % 10 = 5
So 190717-38-5 is a valid CAS Registry Number.
