Check Digit Verification of cas no
The CAS Registry Mumber 186046-59-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,0,4 and 6 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 186046-59:
(8*1)+(7*8)+(6*6)+(5*0)+(4*4)+(3*6)+(2*5)+(1*9)=153
153 % 10 = 3
So 186046-59-3 is a valid CAS Registry Number.
