Check Digit Verification of cas no
The CAS Registry Mumber 158734-92-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,7,3 and 4 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 158734-92:
(8*1)+(7*5)+(6*8)+(5*7)+(4*3)+(3*4)+(2*9)+(1*2)=170
170 % 10 = 0
So 158734-92-0 is a valid CAS Registry Number.
