72238-04-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72238-04-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,2,3 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 72238-04:
(7*7)+(6*2)+(5*2)+(4*3)+(3*8)+(2*0)+(1*4)=111
111 % 10 = 1
So 72238-04-1 is a valid CAS Registry Number.
