Check Digit Verification of cas no

The CAS Registry Mumber 1257628-99-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,6,2 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1257628-99:
(9*1)+(8*2)+(7*5)+(6*7)+(5*6)+(4*2)+(3*8)+(2*9)+(1*9)=191
191 % 10 = 1
So 1257628-99-1 is a valid CAS Registry Number.
