1256095-52-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1256095-52-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,0,9 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1256095-52:
(9*1)+(8*2)+(7*5)+(6*6)+(5*0)+(4*9)+(3*5)+(2*5)+(1*2)=159
159 % 10 = 9
So 1256095-52-9 is a valid CAS Registry Number.
