Check Digit Verification of cas no
The CAS Registry Mumber 1450877-56-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,0,8,7 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1450877-56:
(9*1)+(8*4)+(7*5)+(6*0)+(5*8)+(4*7)+(3*7)+(2*5)+(1*6)=181
181 % 10 = 1
So 1450877-56-1 is a valid CAS Registry Number.
