81699-92-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81699-92-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,9 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 81699-92:
(7*8)+(6*1)+(5*6)+(4*9)+(3*9)+(2*9)+(1*2)=175
175 % 10 = 5
So 81699-92-5 is a valid CAS Registry Number.
