1399666-10-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1399666-10-4 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, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1399666-10:
(9*1)+(8*3)+(7*9)+(6*9)+(5*6)+(4*6)+(3*6)+(2*1)+(1*0)=224
224 % 10 = 4
So 1399666-10-4 is a valid CAS Registry Number.
