144978-13-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144978-13-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,9,7 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 144978-13:
(8*1)+(7*4)+(6*4)+(5*9)+(4*7)+(3*8)+(2*1)+(1*3)=162
162 % 10 = 2
So 144978-13-2 is a valid CAS Registry Number.
