139434-94-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139434-94-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,4,3 and 4 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 139434-94:
(8*1)+(7*3)+(6*9)+(5*4)+(4*3)+(3*4)+(2*9)+(1*4)=149
149 % 10 = 9
So 139434-94-9 is a valid CAS Registry Number.
