134939-02-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134939-02-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,9,3 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 134939-02:
(8*1)+(7*3)+(6*4)+(5*9)+(4*3)+(3*9)+(2*0)+(1*2)=139
139 % 10 = 9
So 134939-02-9 is a valid CAS Registry Number.
