Check Digit Verification of cas no
The CAS Registry Mumber 287719-29-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,7,7,1 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 287719-29:
(8*2)+(7*8)+(6*7)+(5*7)+(4*1)+(3*9)+(2*2)+(1*9)=193
193 % 10 = 3
So 287719-29-3 is a valid CAS Registry Number.
