Check Digit Verification of cas no
The CAS Registry Mumber 300677-90-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,0,6,7 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 300677-90:
(8*3)+(7*0)+(6*0)+(5*6)+(4*7)+(3*7)+(2*9)+(1*0)=121
121 % 10 = 1
So 300677-90-1 is a valid CAS Registry Number.
