Check Digit Verification of cas no
The CAS Registry Mumber 658713-41-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,8,7,1 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 658713-41:
(8*6)+(7*5)+(6*8)+(5*7)+(4*1)+(3*3)+(2*4)+(1*1)=188
188 % 10 = 8
So 658713-41-8 is a valid CAS Registry Number.
