Check Digit Verification of cas no
The CAS Registry Mumber 169267-83-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,2,6 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 169267-83:
(8*1)+(7*6)+(6*9)+(5*2)+(4*6)+(3*7)+(2*8)+(1*3)=178
178 % 10 = 8
So 169267-83-8 is a valid CAS Registry Number.
