140934-41-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140934-41-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,9,3 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 140934-41:
(8*1)+(7*4)+(6*0)+(5*9)+(4*3)+(3*4)+(2*4)+(1*1)=114
114 % 10 = 4
So 140934-41-4 is a valid CAS Registry Number.
