52816-32-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 52816-32-7 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 6 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 52816-32:
(7*5)+(6*2)+(5*8)+(4*1)+(3*6)+(2*3)+(1*2)=117
117 % 10 = 7
So 52816-32-7 is a valid CAS Registry Number.
