139563-96-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139563-96-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,5,6 and 3 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 139563-96:
(8*1)+(7*3)+(6*9)+(5*5)+(4*6)+(3*3)+(2*9)+(1*6)=165
165 % 10 = 5
So 139563-96-5 is a valid CAS Registry Number.
