Check Digit Verification of cas no

The CAS Registry Mumber 27956-20-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,9,5 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 27956-20:
(7*2)+(6*7)+(5*9)+(4*5)+(3*6)+(2*2)+(1*0)=143
143 % 10 = 3
So 27956-20-3 is a valid CAS Registry Number.
