Check Digit Verification of cas no
The CAS Registry Mumber 149400-33-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,4,0 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 149400-33:
(8*1)+(7*4)+(6*9)+(5*4)+(4*0)+(3*0)+(2*3)+(1*3)=119
119 % 10 = 9
So 149400-33-9 is a valid CAS Registry Number.
