904744-95-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 904744-95-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,4,7,4 and 4 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 904744-95:
(8*9)+(7*0)+(6*4)+(5*7)+(4*4)+(3*4)+(2*9)+(1*5)=182
182 % 10 = 2
So 904744-95-2 is a valid CAS Registry Number.
