52819-68-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 52819-68-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,8,1 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 52819-68:
(7*5)+(6*2)+(5*8)+(4*1)+(3*9)+(2*6)+(1*8)=138
138 % 10 = 8
So 52819-68-8 is a valid CAS Registry Number.
