176042-30-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 176042-30-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,0,4 and 2 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 176042-30:
(8*1)+(7*7)+(6*6)+(5*0)+(4*4)+(3*2)+(2*3)+(1*0)=121
121 % 10 = 1
So 176042-30-1 is a valid CAS Registry Number.
