The CAS Registry Mumber 916234-05-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,6,2,3 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 916234-05:
(8*9)+(7*1)+(6*6)+(5*2)+(4*3)+(3*4)+(2*0)+(1*5)=154
154 % 10 = 4
So 916234-05-4 is a valid CAS Registry Number.
