142457-79-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142457-79-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,4,5 and 7 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 142457-79:
(8*1)+(7*4)+(6*2)+(5*4)+(4*5)+(3*7)+(2*7)+(1*9)=132
132 % 10 = 2
So 142457-79-2 is a valid CAS Registry Number.
