Check Digit Verification of cas no
The CAS Registry Mumber 142095-81-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,0,9 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 142095-81:
(8*1)+(7*4)+(6*2)+(5*0)+(4*9)+(3*5)+(2*8)+(1*1)=116
116 % 10 = 6
So 142095-81-6 is a valid CAS Registry Number.
