Check Digit Verification of cas no
The CAS Registry Mumber 17478-82-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,4,7 and 8 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 17478-82:
(7*1)+(6*7)+(5*4)+(4*7)+(3*8)+(2*8)+(1*2)=139
139 % 10 = 9
So 17478-82-9 is a valid CAS Registry Number.
