637771-20-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 637771-20-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,7,7,7 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 637771-20:
(8*6)+(7*3)+(6*7)+(5*7)+(4*7)+(3*1)+(2*2)+(1*0)=181
181 % 10 = 1
So 637771-20-1 is a valid CAS Registry Number.
