Check Digit Verification of cas no
The CAS Registry Mumber 189287-72-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,2,8 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 189287-72:
(8*1)+(7*8)+(6*9)+(5*2)+(4*8)+(3*7)+(2*7)+(1*2)=197
197 % 10 = 7
So 189287-72-7 is a valid CAS Registry Number.
