135080-29-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 135080-29-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,0,8 and 0 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 135080-29:
(8*1)+(7*3)+(6*5)+(5*0)+(4*8)+(3*0)+(2*2)+(1*9)=104
104 % 10 = 4
So 135080-29-4 is a valid CAS Registry Number.
