The CAS Registry Mumber 956904-39-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,6,9,0 and 4 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 956904-39:
(8*9)+(7*5)+(6*6)+(5*9)+(4*0)+(3*4)+(2*3)+(1*9)=215
215 % 10 = 5
So 956904-39-5 is a valid CAS Registry Number.
