72436-95-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72436-95-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,4,3 and 6 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 72436-95:
(7*7)+(6*2)+(5*4)+(4*3)+(3*6)+(2*9)+(1*5)=134
134 % 10 = 4
So 72436-95-4 is a valid CAS Registry Number.
