Check Digit Verification of cas no
The CAS Registry Mumber 3627-47-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,2 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3627-47:
(6*3)+(5*6)+(4*2)+(3*7)+(2*4)+(1*7)=92
92 % 10 = 2
So 3627-47-2 is a valid CAS Registry Number.
