Check Digit Verification of cas no
The CAS Registry Mumber 148238-44-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,2,3 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 148238-44:
(8*1)+(7*4)+(6*8)+(5*2)+(4*3)+(3*8)+(2*4)+(1*4)=142
142 % 10 = 2
So 148238-44-2 is a valid CAS Registry Number.
