782389-43-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 782389-43-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,8,2,3,8 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.Calculate Digit Verification of CAS Registry Number 782389-43:
(8*7)+(7*8)+(6*2)+(5*3)+(4*8)+(3*9)+(2*4)+(1*3)=209
209 % 10 = 9
So 782389-43-9 is a valid CAS Registry Number.
