51999-86-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 51999-86-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,9,9 and 9 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 51999-86:
(7*5)+(6*1)+(5*9)+(4*9)+(3*9)+(2*8)+(1*6)=171
171 % 10 = 1
So 51999-86-1 is a valid CAS Registry Number.
