The CAS Registry Mumber 959977-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,9,9,7 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 959977-20:
(8*9)+(7*5)+(6*9)+(5*9)+(4*7)+(3*7)+(2*2)+(1*0)=259
259 % 10 = 9
So 959977-20-9 is a valid CAS Registry Number.
