72565-41-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72565-41-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,5,6 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 72565-41:
(7*7)+(6*2)+(5*5)+(4*6)+(3*5)+(2*4)+(1*1)=134
134 % 10 = 4
So 72565-41-4 is a valid CAS Registry Number.
