1028131-42-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1028131-42-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,8,1,3 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1028131-42:
(9*1)+(8*0)+(7*2)+(6*8)+(5*1)+(4*3)+(3*1)+(2*4)+(1*2)=101
101 % 10 = 1
So 1028131-42-1 is a valid CAS Registry Number.
