238398-39-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 238398-39-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,8,3,9 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 238398-39:
(8*2)+(7*3)+(6*8)+(5*3)+(4*9)+(3*8)+(2*3)+(1*9)=175
175 % 10 = 5
So 238398-39-5 is a valid CAS Registry Number.
