114376-75-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 114376-75-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,3,7 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 114376-75:
(8*1)+(7*1)+(6*4)+(5*3)+(4*7)+(3*6)+(2*7)+(1*5)=119
119 % 10 = 9
So 114376-75-9 is a valid CAS Registry Number.
