142131-03-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142131-03-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,1,3 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 142131-03:
(8*1)+(7*4)+(6*2)+(5*1)+(4*3)+(3*1)+(2*0)+(1*3)=71
71 % 10 = 1
So 142131-03-1 is a valid CAS Registry Number.
