Check Digit Verification of cas no
The CAS Registry Mumber 142738-84-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,7,3 and 8 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 142738-84:
(8*1)+(7*4)+(6*2)+(5*7)+(4*3)+(3*8)+(2*8)+(1*4)=139
139 % 10 = 9
So 142738-84-9 is a valid CAS Registry Number.
