864755-52-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 864755-52-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,4,7,5 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 864755-52:
(8*8)+(7*6)+(6*4)+(5*7)+(4*5)+(3*5)+(2*5)+(1*2)=212
212 % 10 = 2
So 864755-52-2 is a valid CAS Registry Number.
