1399666-26-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1399666-26-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,9,6,6 and 6 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1399666-26:
(9*1)+(8*3)+(7*9)+(6*9)+(5*6)+(4*6)+(3*6)+(2*2)+(1*6)=232
232 % 10 = 2
So 1399666-26-2 is a valid CAS Registry Number.
