119728-95-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119728-95-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,7,2 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 119728-95:
(8*1)+(7*1)+(6*9)+(5*7)+(4*2)+(3*8)+(2*9)+(1*5)=159
159 % 10 = 9
So 119728-95-9 is a valid CAS Registry Number.
