Check Digit Verification of cas no
The CAS Registry Mumber 156604-34-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,6,0 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 156604-34:
(8*1)+(7*5)+(6*6)+(5*6)+(4*0)+(3*4)+(2*3)+(1*4)=131
131 % 10 = 1
So 156604-34-1 is a valid CAS Registry Number.
