139665-11-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139665-11-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,6 and 5 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139665-11:
(8*1)+(7*3)+(6*9)+(5*6)+(4*6)+(3*5)+(2*1)+(1*1)=155
155 % 10 = 5
So 139665-11-5 is a valid CAS Registry Number.
