52802-87-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 52802-87-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,8,0 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 52802-87:
(7*5)+(6*2)+(5*8)+(4*0)+(3*2)+(2*8)+(1*7)=116
116 % 10 = 6
So 52802-87-6 is a valid CAS Registry Number.
