81564-48-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81564-48-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,5,6 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 81564-48:
(7*8)+(6*1)+(5*5)+(4*6)+(3*4)+(2*4)+(1*8)=139
139 % 10 = 9
So 81564-48-9 is a valid CAS Registry Number.
