91859-41-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91859-41-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,5 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 91859-41:
(7*9)+(6*1)+(5*8)+(4*5)+(3*9)+(2*4)+(1*1)=165
165 % 10 = 5
So 91859-41-5 is a valid CAS Registry Number.
