The CAS Registry Mumber 331948-65-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,1,9,4 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 331948-65:
(8*3)+(7*3)+(6*1)+(5*9)+(4*4)+(3*8)+(2*6)+(1*5)=153
153 % 10 = 3
So 331948-65-3 is a valid CAS Registry Number.
