1389321-66-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1389321-66-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,9,3,2 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1389321-66:
(9*1)+(8*3)+(7*8)+(6*9)+(5*3)+(4*2)+(3*1)+(2*6)+(1*6)=187
187 % 10 = 7
So 1389321-66-7 is a valid CAS Registry Number.
