Check Digit Verification of cas no
The CAS Registry Mumber 41991-85-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,9,9 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 41991-85:
(7*4)+(6*1)+(5*9)+(4*9)+(3*1)+(2*8)+(1*5)=139
139 % 10 = 9
So 41991-85-9 is a valid CAS Registry Number.
