50550-37-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 50550-37-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,5,5 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 50550-37:
(7*5)+(6*0)+(5*5)+(4*5)+(3*0)+(2*3)+(1*7)=93
93 % 10 = 3
So 50550-37-3 is a valid CAS Registry Number.
