37715-33-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 37715-33-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,7,1 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 37715-33:
(7*3)+(6*7)+(5*7)+(4*1)+(3*5)+(2*3)+(1*3)=126
126 % 10 = 6
So 37715-33-6 is a valid CAS Registry Number.
