139058-52-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139058-52-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,0,5 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 139058-52:
(8*1)+(7*3)+(6*9)+(5*0)+(4*5)+(3*8)+(2*5)+(1*2)=139
139 % 10 = 9
So 139058-52-9 is a valid CAS Registry Number.
