Check Digit Verification of cas no
The CAS Registry Mumber 931405-32-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,1,4,0 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 931405-32:
(8*9)+(7*3)+(6*1)+(5*4)+(4*0)+(3*5)+(2*3)+(1*2)=142
142 % 10 = 2
So 931405-32-2 is a valid CAS Registry Number.
