1197197-07-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1197197-07-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,7,1,9 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1197197-07:
(9*1)+(8*1)+(7*9)+(6*7)+(5*1)+(4*9)+(3*7)+(2*0)+(1*7)=191
191 % 10 = 1
So 1197197-07-1 is a valid CAS Registry Number.
