553638-79-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 553638-79-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,3,6,3 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 553638-79:
(8*5)+(7*5)+(6*3)+(5*6)+(4*3)+(3*8)+(2*7)+(1*9)=182
182 % 10 = 2
So 553638-79-2 is a valid CAS Registry Number.
