Check Digit Verification of cas no
The CAS Registry Mumber 6369-47-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,6 and 9 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6369-47:
(6*6)+(5*3)+(4*6)+(3*9)+(2*4)+(1*7)=117
117 % 10 = 7
So 6369-47-7 is a valid CAS Registry Number.
