1240159-58-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1240159-58-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,1,5 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1240159-58:
(9*1)+(8*2)+(7*4)+(6*0)+(5*1)+(4*5)+(3*9)+(2*5)+(1*8)=123
123 % 10 = 3
So 1240159-58-3 is a valid CAS Registry Number.
