1414948-65-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1414948-65-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,4,9,4 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1414948-65:
(9*1)+(8*4)+(7*1)+(6*4)+(5*9)+(4*4)+(3*8)+(2*6)+(1*5)=174
174 % 10 = 4
So 1414948-65-4 is a valid CAS Registry Number.
