939984-91-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 939984-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,9,9,8 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 939984-91:
(8*9)+(7*3)+(6*9)+(5*9)+(4*8)+(3*4)+(2*9)+(1*1)=255
255 % 10 = 5
So 939984-91-5 is a valid CAS Registry Number.
