71918-99-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71918-99-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,9,1 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 71918-99:
(7*7)+(6*1)+(5*9)+(4*1)+(3*8)+(2*9)+(1*9)=155
155 % 10 = 5
So 71918-99-5 is a valid CAS Registry Number.
