116159-59-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116159-59-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,1,5 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 116159-59:
(8*1)+(7*1)+(6*6)+(5*1)+(4*5)+(3*9)+(2*5)+(1*9)=122
122 % 10 = 2
So 116159-59-2 is a valid CAS Registry Number.
