139280-62-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139280-62-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,8 and 0 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 139280-62:
(8*1)+(7*3)+(6*9)+(5*2)+(4*8)+(3*0)+(2*6)+(1*2)=139
139 % 10 = 9
So 139280-62-9 is a valid CAS Registry Number.
