505053-16-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 505053-16-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,5,0,5 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 505053-16:
(8*5)+(7*0)+(6*5)+(5*0)+(4*5)+(3*3)+(2*1)+(1*6)=107
107 % 10 = 7
So 505053-16-7 is a valid CAS Registry Number.
