Check Digit Verification of cas no
The CAS Registry Mumber 116938-56-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,9,3 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 116938-56:
(8*1)+(7*1)+(6*6)+(5*9)+(4*3)+(3*8)+(2*5)+(1*6)=148
148 % 10 = 8
So 116938-56-8 is a valid CAS Registry Number.
