Check Digit Verification of cas no
The CAS Registry Mumber 154367-05-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,3,6 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 154367-05:
(8*1)+(7*5)+(6*4)+(5*3)+(4*6)+(3*7)+(2*0)+(1*5)=132
132 % 10 = 2
So 154367-05-2 is a valid CAS Registry Number.
