Check Digit Verification of cas no

The CAS Registry Mumber 901451-18-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,1,4,5 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 901451-18:
(8*9)+(7*0)+(6*1)+(5*4)+(4*5)+(3*1)+(2*1)+(1*8)=131
131 % 10 = 1
So 901451-18-1 is a valid CAS Registry Number.
