Check Digit Verification of cas no

The CAS Registry Mumber 1293997-30-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,3,9,9 and 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1293997-30:
(9*1)+(8*2)+(7*9)+(6*3)+(5*9)+(4*9)+(3*7)+(2*3)+(1*0)=214
214 % 10 = 4
So 1293997-30-4 is a valid CAS Registry Number.
