53438-59-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 53438-59-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,4,3 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 53438-59:
(7*5)+(6*3)+(5*4)+(4*3)+(3*8)+(2*5)+(1*9)=128
128 % 10 = 8
So 53438-59-8 is a valid CAS Registry Number.
