Check Digit Verification of cas no

The CAS Registry Mumber 136137-19-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,1,3 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 136137-19:
(8*1)+(7*3)+(6*6)+(5*1)+(4*3)+(3*7)+(2*1)+(1*9)=114
114 % 10 = 4
So 136137-19-4 is a valid CAS Registry Number.
