Check Digit Verification of cas no

The CAS Registry Mumber 1201804-20-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,1,8,0 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1201804-20:
(9*1)+(8*2)+(7*0)+(6*1)+(5*8)+(4*0)+(3*4)+(2*2)+(1*0)=87
87 % 10 = 7
So 1201804-20-7 is a valid CAS Registry Number.
