Check Digit Verification of cas no
The CAS Registry Mumber 1416985-23-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,6,9,8 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1416985-23:
(9*1)+(8*4)+(7*1)+(6*6)+(5*9)+(4*8)+(3*5)+(2*2)+(1*3)=183
183 % 10 = 3
So 1416985-23-3 is a valid CAS Registry Number.
