637338-16-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 637338-16-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,7,3,3 and 8 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 637338-16:
(8*6)+(7*3)+(6*7)+(5*3)+(4*3)+(3*8)+(2*1)+(1*6)=170
170 % 10 = 0
So 637338-16-0 is a valid CAS Registry Number.
