1389321-61-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1389321-61-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,9,3,2 and 1 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1389321-61:
(9*1)+(8*3)+(7*8)+(6*9)+(5*3)+(4*2)+(3*1)+(2*6)+(1*1)=182
182 % 10 = 2
So 1389321-61-2 is a valid CAS Registry Number.
