Check Digit Verification of cas no
The CAS Registry Mumber 1417900-08-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,7,9,0 and 0 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1417900-08:
(9*1)+(8*4)+(7*1)+(6*7)+(5*9)+(4*0)+(3*0)+(2*0)+(1*8)=143
143 % 10 = 3
So 1417900-08-3 is a valid CAS Registry Number.
