Check Digit Verification of cas no
The CAS Registry Mumber 8011-86-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,1 and 1 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 8011-86:
(6*8)+(5*0)+(4*1)+(3*1)+(2*8)+(1*6)=77
77 % 10 = 7
So 8011-86-7 is a valid CAS Registry Number.
