1428642-40-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1428642-40-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,6,4 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1428642-40:
(9*1)+(8*4)+(7*2)+(6*8)+(5*6)+(4*4)+(3*2)+(2*4)+(1*0)=163
163 % 10 = 3
So 1428642-40-3 is a valid CAS Registry Number.
