1240515-59-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1240515-59-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,5,1 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1240515-59:
(9*1)+(8*2)+(7*4)+(6*0)+(5*5)+(4*1)+(3*5)+(2*5)+(1*9)=116
116 % 10 = 6
So 1240515-59-6 is a valid CAS Registry Number.
