1439984-81-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1439984-81-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,9,9,8 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1439984-81:
(9*1)+(8*4)+(7*3)+(6*9)+(5*9)+(4*8)+(3*4)+(2*8)+(1*1)=222
222 % 10 = 2
So 1439984-81-2 is a valid CAS Registry Number.
