1240508-07-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1240508-07-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,5,0 and 8 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1240508-07:
(9*1)+(8*2)+(7*4)+(6*0)+(5*5)+(4*0)+(3*8)+(2*0)+(1*7)=109
109 % 10 = 9
So 1240508-07-9 is a valid CAS Registry Number.
