647841-37-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 647841-37-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,7,8,4 and 1 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 647841-37:
(8*6)+(7*4)+(6*7)+(5*8)+(4*4)+(3*1)+(2*3)+(1*7)=190
190 % 10 = 0
So 647841-37-0 is a valid CAS Registry Number.
