Check Digit Verification of cas no
The CAS Registry Mumber 3179-84-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,7 and 9 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3179-84:
(6*3)+(5*1)+(4*7)+(3*9)+(2*8)+(1*4)=98
98 % 10 = 8
So 3179-84-8 is a valid CAS Registry Number.
