78044-05-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78044-05-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,0,4 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 78044-05:
(7*7)+(6*8)+(5*0)+(4*4)+(3*4)+(2*0)+(1*5)=130
130 % 10 = 0
So 78044-05-0 is a valid CAS Registry Number.
