Check Digit Verification of cas no
The CAS Registry Mumber 1443667-05-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,3,6,6 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1443667-05:
(9*1)+(8*4)+(7*4)+(6*3)+(5*6)+(4*6)+(3*7)+(2*0)+(1*5)=167
167 % 10 = 7
So 1443667-05-7 is a valid CAS Registry Number.
