1040138-38-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1040138-38-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,0,1,3 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1040138-38:
(9*1)+(8*0)+(7*4)+(6*0)+(5*1)+(4*3)+(3*8)+(2*3)+(1*8)=92
92 % 10 = 2
So 1040138-38-2 is a valid CAS Registry Number.
