Check Digit Verification of cas no
The CAS Registry Mumber 193806-58-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,8,0 and 6 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 193806-58:
(8*1)+(7*9)+(6*3)+(5*8)+(4*0)+(3*6)+(2*5)+(1*8)=165
165 % 10 = 5
So 193806-58-5 is a valid CAS Registry Number.
