142389-65-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142389-65-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,3,8 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 142389-65:
(8*1)+(7*4)+(6*2)+(5*3)+(4*8)+(3*9)+(2*6)+(1*5)=139
139 % 10 = 9
So 142389-65-9 is a valid CAS Registry Number.
