161297-40-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 161297-40-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,2,9 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 161297-40:
(8*1)+(7*6)+(6*1)+(5*2)+(4*9)+(3*7)+(2*4)+(1*0)=131
131 % 10 = 1
So 161297-40-1 is a valid CAS Registry Number.
