Check Digit Verification of cas no
The CAS Registry Mumber 119930-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,9,3 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 119930-91:
(8*1)+(7*1)+(6*9)+(5*9)+(4*3)+(3*0)+(2*9)+(1*1)=145
145 % 10 = 5
So 119930-91-5 is a valid CAS Registry Number.
