Check Digit Verification of cas no
The CAS Registry Mumber 205178-61-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,1,7 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 205178-61:
(8*2)+(7*0)+(6*5)+(5*1)+(4*7)+(3*8)+(2*6)+(1*1)=116
116 % 10 = 6
So 205178-61-6 is a valid CAS Registry Number.
