72196-85-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72196-85-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,1,9 and 6 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 72196-85:
(7*7)+(6*2)+(5*1)+(4*9)+(3*6)+(2*8)+(1*5)=141
141 % 10 = 1
So 72196-85-1 is a valid CAS Registry Number.
