1017684-56-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1017684-56-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,7,6,8 and 4 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1017684-56:
(9*1)+(8*0)+(7*1)+(6*7)+(5*6)+(4*8)+(3*4)+(2*5)+(1*6)=148
148 % 10 = 8
So 1017684-56-8 is a valid CAS Registry Number.
