139930-89-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139930-89-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,3 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 139930-89:
(8*1)+(7*3)+(6*9)+(5*9)+(4*3)+(3*0)+(2*8)+(1*9)=165
165 % 10 = 5
So 139930-89-5 is a valid CAS Registry Number.
