72844-68-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72844-68-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,8,4 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 72844-68:
(7*7)+(6*2)+(5*8)+(4*4)+(3*4)+(2*6)+(1*8)=149
149 % 10 = 9
So 72844-68-9 is a valid CAS Registry Number.
