1040233-59-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1040233-59-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,0,2,3 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1040233-59:
(9*1)+(8*0)+(7*4)+(6*0)+(5*2)+(4*3)+(3*3)+(2*5)+(1*9)=87
87 % 10 = 7
So 1040233-59-7 is a valid CAS Registry Number.
