1428643-51-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1428643-51-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,6,4 and 3 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1428643-51:
(9*1)+(8*4)+(7*2)+(6*8)+(5*6)+(4*4)+(3*3)+(2*5)+(1*1)=169
169 % 10 = 9
So 1428643-51-9 is a valid CAS Registry Number.
