81797-99-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81797-99-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,7,9 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81797-99:
(7*8)+(6*1)+(5*7)+(4*9)+(3*7)+(2*9)+(1*9)=181
181 % 10 = 1
So 81797-99-1 is a valid CAS Registry Number.
