Check Digit Verification of cas no

The CAS Registry Mumber 138747-90-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,7,4 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 138747-90:
(8*1)+(7*3)+(6*8)+(5*7)+(4*4)+(3*7)+(2*9)+(1*0)=167
167 % 10 = 7
So 138747-90-7 is a valid CAS Registry Number.
