16831-49-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 16831-49-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,3 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 16831-49:
(7*1)+(6*6)+(5*8)+(4*3)+(3*1)+(2*4)+(1*9)=115
115 % 10 = 5
So 16831-49-5 is a valid CAS Registry Number.
