Check Digit Verification of cas no
The CAS Registry Mumber 142078-52-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,0,7 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 142078-52:
(8*1)+(7*4)+(6*2)+(5*0)+(4*7)+(3*8)+(2*5)+(1*2)=112
112 % 10 = 2
So 142078-52-2 is a valid CAS Registry Number.
