Check Digit Verification of cas no

The CAS Registry Mumber 148887-46-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,8,8 and 7 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 148887-46:
(8*1)+(7*4)+(6*8)+(5*8)+(4*8)+(3*7)+(2*4)+(1*6)=191
191 % 10 = 1
So 148887-46-1 is a valid CAS Registry Number.
