637765-41-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 637765-41-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,7,7,6 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 637765-41:
(8*6)+(7*3)+(6*7)+(5*7)+(4*6)+(3*5)+(2*4)+(1*1)=194
194 % 10 = 4
So 637765-41-4 is a valid CAS Registry Number.
