142741-72-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142741-72-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,7,4 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 142741-72:
(8*1)+(7*4)+(6*2)+(5*7)+(4*4)+(3*1)+(2*7)+(1*2)=118
118 % 10 = 8
So 142741-72-8 is a valid CAS Registry Number.
