547738-53-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 547738-53-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,7,7,3 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 547738-53:
(8*5)+(7*4)+(6*7)+(5*7)+(4*3)+(3*8)+(2*5)+(1*3)=194
194 % 10 = 4
So 547738-53-4 is a valid CAS Registry Number.
