500615-68-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 500615-68-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,0,6,1 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 500615-68:
(8*5)+(7*0)+(6*0)+(5*6)+(4*1)+(3*5)+(2*6)+(1*8)=109
109 % 10 = 9
So 500615-68-9 is a valid CAS Registry Number.
