15999-99-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 15999-99-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,9,9 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 15999-99:
(7*1)+(6*5)+(5*9)+(4*9)+(3*9)+(2*9)+(1*9)=172
172 % 10 = 2
So 15999-99-2 is a valid CAS Registry Number.
