1425865-33-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1425865-33-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,5,8,6 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1425865-33:
(9*1)+(8*4)+(7*2)+(6*5)+(5*8)+(4*6)+(3*5)+(2*3)+(1*3)=173
173 % 10 = 3
So 1425865-33-3 is a valid CAS Registry Number.
