197235-78-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 197235-78-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,2,3 and 5 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 197235-78:
(8*1)+(7*9)+(6*7)+(5*2)+(4*3)+(3*5)+(2*7)+(1*8)=172
172 % 10 = 2
So 197235-78-2 is a valid CAS Registry Number.
