58803-37-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 58803-37-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,8,0 and 3 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 58803-37:
(7*5)+(6*8)+(5*8)+(4*0)+(3*3)+(2*3)+(1*7)=145
145 % 10 = 5
So 58803-37-5 is a valid CAS Registry Number.
