142389-47-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142389-47-7 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, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 142389-47:
(8*1)+(7*4)+(6*2)+(5*3)+(4*8)+(3*9)+(2*4)+(1*7)=137
137 % 10 = 7
So 142389-47-7 is a valid CAS Registry Number.
