Check Digit Verification of cas no
The CAS Registry Mumber 111492-15-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,4,9 and 2 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 111492-15:
(8*1)+(7*1)+(6*1)+(5*4)+(4*9)+(3*2)+(2*1)+(1*5)=90
90 % 10 = 0
So 111492-15-0 is a valid CAS Registry Number.
