114368-81-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 114368-81-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,3,6 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 114368-81:
(8*1)+(7*1)+(6*4)+(5*3)+(4*6)+(3*8)+(2*8)+(1*1)=119
119 % 10 = 9
So 114368-81-9 is a valid CAS Registry Number.
