Check Digit Verification of cas no

The CAS Registry Mumber 136744-22-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,7,4 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 136744-22:
(8*1)+(7*3)+(6*6)+(5*7)+(4*4)+(3*4)+(2*2)+(1*2)=134
134 % 10 = 4
So 136744-22-4 is a valid CAS Registry Number.
