142230-57-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142230-57-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,2,3 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 142230-57:
(8*1)+(7*4)+(6*2)+(5*2)+(4*3)+(3*0)+(2*5)+(1*7)=87
87 % 10 = 7
So 142230-57-7 is a valid CAS Registry Number.
