600727-37-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 600727-37-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,0,0,7,2 and 7 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 600727-37:
(8*6)+(7*0)+(6*0)+(5*7)+(4*2)+(3*7)+(2*3)+(1*7)=125
125 % 10 = 5
So 600727-37-5 is a valid CAS Registry Number.
