Check Digit Verification of cas no
The CAS Registry Mumber 187219-45-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,2,1 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 187219-45:
(8*1)+(7*8)+(6*7)+(5*2)+(4*1)+(3*9)+(2*4)+(1*5)=160
160 % 10 = 0
So 187219-45-0 is a valid CAS Registry Number.
