116775-42-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116775-42-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,7,7 and 5 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 116775-42:
(8*1)+(7*1)+(6*6)+(5*7)+(4*7)+(3*5)+(2*4)+(1*2)=139
139 % 10 = 9
So 116775-42-9 is a valid CAS Registry Number.
