72844-65-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72844-65-6 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 5 respectively.
Calculate Digit Verification of CAS Registry Number 72844-65:
(7*7)+(6*2)+(5*8)+(4*4)+(3*4)+(2*6)+(1*5)=146
146 % 10 = 6
So 72844-65-6 is a valid CAS Registry Number.
