Check Digit Verification of cas no

The CAS Registry Mumber 1377791-72-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,7,7,9 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1377791-72:
(9*1)+(8*3)+(7*7)+(6*7)+(5*7)+(4*9)+(3*1)+(2*7)+(1*2)=214
214 % 10 = 4
