Check Digit Verification of cas no
The CAS Registry Mumber 3087-16-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,8 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3087-16:
(6*3)+(5*0)+(4*8)+(3*7)+(2*1)+(1*6)=79
79 % 10 = 9
So 3087-16-9 is a valid CAS Registry Number.
