Check Digit Verification of cas no

The CAS Registry Mumber 351069-92-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,1,0,6 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 351069-92:
(8*3)+(7*5)+(6*1)+(5*0)+(4*6)+(3*9)+(2*9)+(1*2)=136
136 % 10 = 6
So 351069-92-6 is a valid CAS Registry Number.
