Check Digit Verification of cas no

The CAS Registry Mumber 1626400-01-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,6,4,0 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1626400-01:
(9*1)+(8*6)+(7*2)+(6*6)+(5*4)+(4*0)+(3*0)+(2*0)+(1*1)=128
128 % 10 = 8
So 1626400-01-8 is a valid CAS Registry Number.

5-(Methylthio)tetrazoles as versatile synthons in the stereoselective synthesis of polycyclic pyrazolines via photoinduced intramolecular nitrile imine-alkene 1,3-dipolar cycloaddition

Pla, Daniel,Tan, Derek S.,Gin, David Y.

, p. 2407 - 2415 (2014/05/20)

A key thioether substituent in readily accessible 2-alkyl-5-(methylthio) tetrazoles enables facile photoinduced denitrogenation and intramolecular nitrile imine 1,3-dipolar cycloaddition to afford a wide range of polycyclic pyrazoline products with excellent diastereoselectivity. The methylthio group red-shifts the UV absorbance of the tetrazole, obviating the requirement in all previous substrate systems for at least one aryl substituent, and can subsequently be converted into a variety of other functionalities. This synthetic platform has been applied to the concise total syntheses of the alkaloid natural products (±)-newbouldine and withasomnine. This journal is the Partner Organisations 2014.
