Check Digit Verification of cas no

The CAS Registry Mumber 141899-52-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,8,9 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 141899-52:
(8*1)+(7*4)+(6*1)+(5*8)+(4*9)+(3*9)+(2*5)+(1*2)=157
157 % 10 = 7
So 141899-52-7 is a valid CAS Registry Number.
