Check Digit Verification of cas no
The CAS Registry Mumber 162809-52-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,8,0 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 162809-52:
(8*1)+(7*6)+(6*2)+(5*8)+(4*0)+(3*9)+(2*5)+(1*2)=141
141 % 10 = 1
So 162809-52-1 is a valid CAS Registry Number.
