Check Digit Verification of cas no
The CAS Registry Mumber 161942-89-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,9,4 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 161942-89:
(8*1)+(7*6)+(6*1)+(5*9)+(4*4)+(3*2)+(2*8)+(1*9)=148
148 % 10 = 8
So 161942-89-8 is a valid CAS Registry Number.
