139584-77-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139584-77-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,5,8 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 139584-77:
(8*1)+(7*3)+(6*9)+(5*5)+(4*8)+(3*4)+(2*7)+(1*7)=173
173 % 10 = 3
So 139584-77-3 is a valid CAS Registry Number.
