142683-03-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142683-03-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,6,8 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 142683-03:
(8*1)+(7*4)+(6*2)+(5*6)+(4*8)+(3*3)+(2*0)+(1*3)=122
122 % 10 = 2
So 142683-03-2 is a valid CAS Registry Number.
