1428243-88-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1428243-88-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,2,4 and 3 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1428243-88:
(9*1)+(8*4)+(7*2)+(6*8)+(5*2)+(4*4)+(3*3)+(2*8)+(1*8)=162
162 % 10 = 2
So 1428243-88-2 is a valid CAS Registry Number.
