144872-92-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144872-92-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,8,7 and 2 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 144872-92:
(8*1)+(7*4)+(6*4)+(5*8)+(4*7)+(3*2)+(2*9)+(1*2)=154
154 % 10 = 4
So 144872-92-4 is a valid CAS Registry Number.
