53736-87-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 53736-87-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,7,3 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 53736-87:
(7*5)+(6*3)+(5*7)+(4*3)+(3*6)+(2*8)+(1*7)=141
141 % 10 = 1
So 53736-87-1 is a valid CAS Registry Number.
