1439552-74-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1439552-74-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,9,5,5 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1439552-74:
(9*1)+(8*4)+(7*3)+(6*9)+(5*5)+(4*5)+(3*2)+(2*7)+(1*4)=185
185 % 10 = 5
So 1439552-74-5 is a valid CAS Registry Number.
