297157-04-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 297157-04-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,7,1,5 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 297157-04:
(8*2)+(7*9)+(6*7)+(5*1)+(4*5)+(3*7)+(2*0)+(1*4)=171
171 % 10 = 1
So 297157-04-1 is a valid CAS Registry Number.
