72154-87-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72154-87-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,1,5 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 72154-87:
(7*7)+(6*2)+(5*1)+(4*5)+(3*4)+(2*8)+(1*7)=121
121 % 10 = 1
So 72154-87-1 is a valid CAS Registry Number.
