1428338-39-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1428338-39-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,3,3 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1428338-39:
(9*1)+(8*4)+(7*2)+(6*8)+(5*3)+(4*3)+(3*8)+(2*3)+(1*9)=169
169 % 10 = 9
So 1428338-39-9 is a valid CAS Registry Number.
