53756-58-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 53756-58-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,7,5 and 6 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 53756-58:
(7*5)+(6*3)+(5*7)+(4*5)+(3*6)+(2*5)+(1*8)=144
144 % 10 = 4
So 53756-58-4 is a valid CAS Registry Number.
