928342-27-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 928342-27-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,8,3,4 and 2 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 928342-27:
(8*9)+(7*2)+(6*8)+(5*3)+(4*4)+(3*2)+(2*2)+(1*7)=182
182 % 10 = 2
So 928342-27-2 is a valid CAS Registry Number.
