Check Digit Verification of cas no
The CAS Registry Mumber 169375-55-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,3,7 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 169375-55:
(8*1)+(7*6)+(6*9)+(5*3)+(4*7)+(3*5)+(2*5)+(1*5)=177
177 % 10 = 7
So 169375-55-7 is a valid CAS Registry Number.
