297157-10-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 297157-10-9 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, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 297157-10:
(8*2)+(7*9)+(6*7)+(5*1)+(4*5)+(3*7)+(2*1)+(1*0)=169
169 % 10 = 9
So 297157-10-9 is a valid CAS Registry Number.
