Check Digit Verification of cas no
The CAS Registry Mumber 1917324-13-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,9,1,7,3,2 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1917324-13:
(9*1)+(8*9)+(7*1)+(6*7)+(5*3)+(4*2)+(3*4)+(2*1)+(1*3)=170
170 % 10 = 0
So 1917324-13-0 is a valid CAS Registry Number.
