Check Digit Verification of cas no
The CAS Registry Mumber 1149618-40-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,9,6,1 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1149618-40:
(9*1)+(8*1)+(7*4)+(6*9)+(5*6)+(4*1)+(3*8)+(2*4)+(1*0)=165
165 % 10 = 5
So 1149618-40-5 is a valid CAS Registry Number.
