1197397-32-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1197397-32-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,7,3,9 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1197397-32:
(9*1)+(8*1)+(7*9)+(6*7)+(5*3)+(4*9)+(3*7)+(2*3)+(1*2)=202
202 % 10 = 2
So 1197397-32-2 is a valid CAS Registry Number.
