Check Digit Verification of cas no
The CAS Registry Mumber 188619-15-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,6,1 and 9 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 188619-15:
(8*1)+(7*8)+(6*8)+(5*6)+(4*1)+(3*9)+(2*1)+(1*5)=180
180 % 10 = 0
So 188619-15-0 is a valid CAS Registry Number.
