1637672-69-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1637672-69-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,7,6,7 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1637672-69:
(9*1)+(8*6)+(7*3)+(6*7)+(5*6)+(4*7)+(3*2)+(2*6)+(1*9)=205
205 % 10 = 5
So 1637672-69-5 is a valid CAS Registry Number.
