939054-92-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 939054-92-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,9,0,5 and 4 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 939054-92:
(8*9)+(7*3)+(6*9)+(5*0)+(4*5)+(3*4)+(2*9)+(1*2)=199
199 % 10 = 9
So 939054-92-9 is a valid CAS Registry Number.
