Check Digit Verification of cas no
The CAS Registry Mumber 3769-58-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,6 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3769-58:
(6*3)+(5*7)+(4*6)+(3*9)+(2*5)+(1*8)=122
122 % 10 = 2
So 3769-58-2 is a valid CAS Registry Number.
