Check Digit Verification of cas no
The CAS Registry Mumber 92142-18-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,1,4 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 92142-18:
(7*9)+(6*2)+(5*1)+(4*4)+(3*2)+(2*1)+(1*8)=112
112 % 10 = 2
So 92142-18-2 is a valid CAS Registry Number.
