Check Digit Verification of cas no

The CAS Registry Mumber 21990-37-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,9 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 21990-37:
(7*2)+(6*1)+(5*9)+(4*9)+(3*0)+(2*3)+(1*7)=114
114 % 10 = 4
So 21990-37-4 is a valid CAS Registry Number.
