Check Digit Verification of cas no
The CAS Registry Mumber 956218-04-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,6,2,1 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 956218-04:
(8*9)+(7*5)+(6*6)+(5*2)+(4*1)+(3*8)+(2*0)+(1*4)=185
185 % 10 = 5
So 956218-04-5 is a valid CAS Registry Number.
