78041-95-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 78041-95-9 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 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 78041-95:
(7*7)+(6*8)+(5*0)+(4*4)+(3*1)+(2*9)+(1*5)=139
139 % 10 = 9
So 78041-95-9 is a valid CAS Registry Number.
