Check Digit Verification of cas no
The CAS Registry Mumber 1020661-22-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,0,6,6 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1020661-22:
(9*1)+(8*0)+(7*2)+(6*0)+(5*6)+(4*6)+(3*1)+(2*2)+(1*2)=86
86 % 10 = 6
So 1020661-22-6 is a valid CAS Registry Number.
