1260157-86-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1260157-86-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,0,1,5 and 7 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1260157-86:
(9*1)+(8*2)+(7*6)+(6*0)+(5*1)+(4*5)+(3*7)+(2*8)+(1*6)=135
135 % 10 = 5
So 1260157-86-5 is a valid CAS Registry Number.
